Pdf
Portable Document Format (PDF) is a file format created by Adobe Systems in 1993 for document exchange. PDF is used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system.
Each PDF file encapsulates a complete description of a fixed-layout 2D document (and, with Acrobat 3D, embedded 3D documents) that includes the text, fonts, images, and 2D vector graphics which compose the documents.
Formerly a proprietary format, PDF was officially released as an open standard on July 1, 2008, and published by the International Organization for Standardization as ISO/IEC 32000-1:2008
More information on how to create pdf documents can be found on http://createpdf.adobe.com/
Mobi
The Mobipocket file format is a binary format for the distribution of eBooks. It is one implementation of the Open eBook Publication format with a number of proprietary extensions. The Open eBook Publication format is developed and specified by the IDPF (International Digital Publishing Forum) an independent organization formerly known as the Open eBook Consortium. As a consequence, the Mobipocket format is based on HTML and is reflowable. Mobipocket supports most features of standard HTML to format and layout text and images.
Prc
PRC is a 3D file format that can be used to embed 3D data in a PDF file.
This highly compressed format facilitates the storage of different representations of a 3D model. For example, you can save only a visual representation that consists of polygons (a tessellation), or you can save the model's exact geometry (B-rep data). Varying levels of compression can be applied to the 3D CAD data when it is converted to the PRC format using Acrobat 3D.
The 3D data stored in PRC format in a PDF is interoperable with Computer Aided Manufacturing (CAM) and Computer Aided Engineering (CAE) applications

Epub
EPUB (electronic publication) is an e-book standard, by the International Digital Publishing Forum (IDPF), which consists of three file format standards (files have the extension .epub), described below. It supersedes the Open eBook standard
EPUB is a free and open standard for "reflowable" content, meaning that the text display can be optimized for the particular display device. Internally, EPUB uses XHTML or DTBook (an XML standard provided by the DAISY Consortium) to represent the text and zip as a packaging format. EPUB includes optional support for Digital Rights Management (DRM).
EPUB became an official standard of the International Digital Publishing Forum (IDPF)in September, 2007, superseding the older Open eBook standard. EPUB consists of three specifications:
Open Publication Structure (OPS) 2.0, contains the formatting of its content.
Open Packaging Format (OPF) 2.0, describes the structure of the .epub file in XML.
OEBPS Container Format (OCF) 1.0, collects all files as ZIP archive.
EPUB files are a new (as of 12 March 2009) experimental feature at Project Gutenberg. Google also announced in August 2009 that it would begin offering public domain books for download in the EPUB format from its Google Books site.
Lit
The Lit standard was introduced by Microsoft, It uses Cleartype Technology for easy reading on small PDA screens. (The ".LIT" stands for "literature"). This format is based on Microsoft Compressed HTML Help format. These books can be purchased and downloaded from online stores for example the Microsoft store http://www.microsoft.com/reader/
Please note, DRM protected LIT files can not be read on the BeBook, they require online activation, which is currently not possible with the BeBook. (and .lit files are not supported in mobipocket or digital editions software)
Txt
.txt is a filename extension for files consisting of text usually contain very little formatting (ex: no bolding or italics). The precise definition of the .txt format is not specified, but typically matches the format accepted by the system terminal or simple text editor. Files with the .txt extension can easily be read or opened by any program that reads text and, for that reason, are considered universal (or platform independent).
The ASCII character set is the most common format for English-language text files, and is generally assumed to be the default file format in many situations. For accented and other non-ASCII characters, it is necessary to choose a character encoding. In many systems, this is chosen on the basis of the default locale setting on the computer it is read on. Common character encodings include ISO 8859-1 for many European languages.
Because many encodings have only a limited repertoire of characters, they are often only usable to represent text in a limited subset of human languages. Unicode is an attempt to create a common standard for representing all known languages, and most known character sets are subsets of the very large Unicode character set. Although there are multiple character encodings available for Unicode, the most common is UTF-8, which has the advantage of being backwards-compatible with ASCII: that is, every ASCII text file is also a UTF-8 text file with identical meaning.
Standard Windows .txt files
Microsoft MS-DOS and Windows use a common text file format, with each line of text separated by a two character combination: CR and LF, which have ASCII codes 13 and 10. It is common for the last line of text not to be terminated with a CR-LF marker, and many text editors (including Notepad) do not automatically insert one on the last line.
Most Windows text files use a form of ANSI, OEM or Unicode encoding. What Windows terminology calls "ANSI encodings" are usually single-byte ISO-8859 encodings, except for in locales such as Chinese, Japanese and Korean that require double-byte character sets. ANSI encodings were traditionally used as default system locales within Windows, before the transition to Unicode. By contrast, OEM encodings, also known as MS-DOS code pages, were defined by IBM for use in the original IBM PC text mode display system. They typically include graphical and line-drawing characters common in full-screen MS-DOS applications. Newer Windows text files may use a Unicode encoding such as UTF-16LE or UTF-8.
fb2
FictionBook is an open XML-based e-book format, which originated and gained popularity in Russia. It is supported by e-book readers such as the BeBook. The FictionBook files have the .fb2 filename extension.
The FictionBook format does not specify the representation of a document, describing its structure instead. For example, there are special tags for epigraphs, verses and quotations. All the ebook metadata, such as the author name, title, and publish information, is also present in the ebook file. Hence, the format is convenient for automatic processing, indexing, and ebook collections management. Moreover, it allows automatic conversion into other formats.
In contrary to other eBook formats (e.g. ePub) FictionBook eBook contains just one xml-like file. Images (and possibly other binary data) are converted to Base64 and reside inside the <binary> tag, this resulting into an eBook being of larger file-size.

doc
The DOC format is native to Microsoft Office Word, but other software, such as the free software word processors OpenOffice.org Writer, and AbiWord, can create and read .doc files. Command line programs for Unix-like operating systems which can convert files from the DOC format to plain text or other standard formats include the wv library, which itself is used directly by AbiWord and as a source of ideas and some coding by KWord. Because the .doc file format was a closed specification for many years, inconsistent handling of the format persists and may cause some loss of formatting information when handling the same file with multiple word processing programs.
html
HTML, which stands for Hyper Text Markup Language, is the predominant markup language for web pages. It provides a means to create structured documents by denoting structural semantics for text such as headings, paragraphs, lists etc as well as for links, quotes, and other items. It allows images and objects to be embedded and can be used to create interactive forms. It is written in the form of HTML elements consisting of "tags" surrounded by angle brackets within the web page content.
rtf
The Rich Text Format (often abbreviated RTF) is a document file format developed by Microsoft in 1987 for cross-platform document interchange. Most word processors are able to read and write RTF documents
RTF is an 8-bit format. That would limit it to ASCII, but RTF can encode characters beyond ASCII by escape sequences. The character escapes are of two types: code page escapes and Unicode escapes. In a code page escape, two hexadecimal digits following an apostrophe are used for denoting a character taken from a Windows code page. For example, if control codes specifying Windows-1256 are present, the sequence 'c8 will encode the Arabic letter beh (ب).
If a Unicode escape is required, the control word u is used, followed by a 16-bit signed decimal integer giving the Unicode codepoint number. For the benefit of programs without Unicode support, this must be followed by the nearest representation of this character in the specified code page. For example, u1576? would give the Arabic letter beh, specifying that older programs which do not have Unicode support should render it as a question mark instead.
The control word uc0 can be used to indicate that subsequent Unicode escape sequences within the current group do not specify a substitution character.

wol
The Web Ontology Language (OWL) is a family of knowledge representation languages for authoring ontologies, and is endorsed by the World Wide Web Consortium.[1] This family of languages is based on two (largely, but not entirely, compatible) semantics: OWL DL and OWL Lite semantics are based on Description Logic,[2] which have attractive and well-understood computational properties, while OWL Full uses a semantic model intended to provide compatibility with RDF Schema. OWL ontologies are most commonly serialized using RDF/XML syntax. OWL is considered one of the fundamental technologies underpinning the Semantic Web, and has attracted both academic and commercial interest.
ppt
Fileformat used for creating presentation in Microsoft Powerpoint
The binary format specification has been available from Microsoft on request, but since February 2008 the .ppt format specification can be freely downloaded.
In Microsoft Office 2007 the binary file formats were replaced as the default format by the new XML based Office Open XML formats, which are published as an open standard. Nevertheless, they are not complete as there are binary blobs inside of the XML files, and several pieces of behaviour are not specified but refer to the observed behaviour of specific versions of Microsoft products.

Chm
Microsoft Compiled HTML Help is a proprietary format for online help files, developed by Microsoft and first released in 1997 as a successor to the Microsoft WinHelp format. It was first introduced with the release of Windows 98, and is still supported and distributed through Windows XP and Vista platforms.
HTML Help files are made with Help authoring tools. Microsoft ships the Help Workshop with supported versions of Microsoft Windows and makes the tool available as a free download. There are also a number of third-party Help authoring tools available.
The Microsoft Reader .LIT file format is basically a modification of the HTML Help CHM format[citation needed]. CHM files are sometimes used for e-books.
In 2002, Microsoft announced some security risks associated with the .CHM format, as well as some security bulletins and patches. They have since announced their intentions not to develop the .CHM format further, and will be moving to a new generation of Windows Help called Microsoft Assistance Markup Language in the Windows Vista operating system
bmp
The BMP file format, sometimes called bitmap or DIB file format (for device-independent bitmap), is an image file format used to store bitmap digital images, especially on Microsoft Windows and OS/2 operating systems.
Many graphical user interfaces use bitmaps in their built-in graphics subsystems;[1] for example, the Microsoft Windows and OS/2 platforms' GDI subsystem, where the specific format used is the Windows and OS/2 bitmap file format, usually named with the file extension of .BMP or .DIB.
jpg
In computing, JPEG is a commonly used method of compression for photographic images. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
JPEG compression is used in a number of image file formats. JPEG/Exif is the most common image format used by digital cameras and other photographic image capture devices; along with JPEG/JFIF, it is the most common format for storing and transmitting photographic images on the World Wide Web. These format variations are often not distinguished, and are simply called JPEG.
png
The Portable Network Graphics (PNG) format was designed to replace the older and simpler GIF format and, to some extent, the much more complex TIFF format. (See the main page or the history page for background information.) Here we'll concentrate on two major uses: the World Wide Web (WWW) and image-editing.
For the Web, PNG really has three main advantages over GIF: alpha channels (variable transparency), gamma correction (cross-platform control of image brightness), and two-dimensional interlacing (a method of progressive display). PNG also compresses better than GIF in almost every case, but the difference is generally only around 5% to 25%, not a large enough factor to encourage folks to switch on that basis alone. One GIF feature that PNG does not try to reproduce is multiple-image support, especially animations; PNG was and is intended to be a single-image format only. (A very PNG-like extension format called MNG was finalized in mid-1999 and is beginning to be supported by various applications, but MNGs and PNGs will have different file extensions and different purposes.)
For image editing, either professional or otherwise, PNG provides a useful format for the storage of intermediate stages of editing. Since PNG's compression is fully lossless--and since it supports up to 48-bit truecolor or 16-bit grayscale--saving, restoring and re-saving an image will not degrade its quality, unlike standard JPEG (even at its highest quality settings). And unlike TIFF, the PNG specification leaves no room for implementors to pick and choose what features they'll support; the result is that a PNG image saved in one app is readable in any other PNG-supporting application. (Note that for transmission of finished truecolor images--especially photographic ones--JPEG is almost always a better choice. Although JPEG's lossy compression can introduce visible artifacts, these can be minimized, and the savings in file size even at high quality levels is much better than is generally possible with a lossless format like PNG. And for black-and-white images, particularly of text or drawings, TIFF's Group 4 fax compression or the JBIG format are often far better than 1-bit grayscale PNG.)
Like GIF and TIFF, PNG is a raster format, which is to say, it represents an image as a two-dimensional array of colored dots (pixels). PNG is explicitly not a vector format, i.e., one that can store shapes (lines, boxes, ellipses, etc.) and be scaled arbitrarily without any loss of quality (generally speaking). For that you probably want SVG or PostScript. (There are some private extensions to PNG that add vector information in addition to PNG's regular pixels--Macromedia's Fireworks does something along those lines--but no valid PNG may omit the pixel data.)
gif
The Graphics Interchange Format (GIF) is a bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability.
The format supports up to 8 bits per pixel, allowing a single image to reference a palette of up to 256 distinct colors chosen from the 24-bit RGB color space. It also supports animations and allows a separate palette of 256 colors for each frame. The color limitation makes the GIF format unsuitable for reproducing color photographs and other images with continuous color, but it is well-suited for simpler images such as graphics or logos with solid areas of color.
GIF images are compressed using the Lempel-Ziv-Welch (LZW) lossless data compression technique to reduce the file size without degrading the visual quality. This compression technique was patented in 1985. Controversy over the licensing agreement between the patent holder, Unisys, and CompuServe in 1994 spurred the development of the Portable Network Graphics (PNG) standard; since then all the relevant patents have expired.
tif
Tagged Image File Format (abbreviated TIFF) is a file format for storing images, including photographs and line art. It is as of 2009 under the control of Adobe Systems. Originally created by the company Aldus[1] for use with what was then called "desktop publishing", the TIFF format is widely supported by image-manipulation applications, by publishing and page layout applications, by scanning, faxing, word processing, optical character recognition and other applications.[2] Adobe Systems, which acquired Aldus, now holds the copyright to the TIFF specification. TIFF has not had a major update since 1992, though several Aldus/Adobe technical notes have been published with minor extensions to the format, and several specifications, including TIFF/EP and TIFF/IT (ISO 12639)[3][4] have been based on the TIFF 6.0 specification.
rar
In computing, RAR is a proprietary archive file format that supports data compression, error recovery, and file spanning. It was developed by a Russian software engineer, Eugene Roshal (hence the name RAR: Roshal ARchive; RAR is also known as a backronym for 'Rational And Reliable'), and is currently licensed by win.rar GmbH.
Zip
The ZIP file format is a data compression and archive format. A ZIP file contains one or more files that have been compressed to reduce file size, or stored as-is. The ZIP file format permits a number of compression algorithms but, as of 2009, the Deflate method continues to be dominant.
ZIP is a simple archive format that compresses every file separately. Compressing files separately allows for individual files to be retrieved without reading through other data; in theory, it may allow better compression by using different algorithms for different files. A caveat to this is that archives containing a large number of small files end up significantly larger than if they were compressed as a single file (the classic example of the latter is the common tar.gz archive which consists of a TAR archive compressed using gzip).
The original ZIP format had a 4GB limit on various things (uncompressed size of a file, compressed size of a file and total size of the archive), as well as a limit of 65535 entries in a zip archive. In version 4.5 of the specification (which is not the same as v4.5 of any particular tool), PKWARE introduced the "ZIP64" format extensions to get around these limitations. Zip64 support is emerging. For example, the File Explorer in Windows XP does not support ZIP64, but the Explorer in Windows Vista does. Likewise - some libraries, such as IO::Compress::Zip in Perl, have new support for ZIP64, while others, such as Java's built-in java.util.zip, still lack it.
The ZIP spec also supports spreading archives across multiple filesystem files. Originally intended for storage of large zip files across multiple 1.44mb floppy disks, this feature is now used for sending zip archives in parts over email, or over other transports or removable media. The FAT filesystem of DOS only has a timestamp resolution of two seconds; ZIP file records mimic this. As a result, the built-in timestamp resolution of files in a ZIP archive is only two seconds, though extra fields can be used to store more accurate timestamps.
Since September 2007, the ZIP specification (APPNOTE.TXT) contains a provision to store file names using UTF-8, finally adding Unicode compatibility to ZIP.
mp3
MPEG-1 Audio Layer 3, more commonly referred to as MP3, is a patented digital audio encoding format using a form of lossy data compression. It is a common audio format for consumer audio storage, as well as a de facto standard of digital audio compression for the transfer and playback of music on digital audio players. MP3 is an audio-specific format that was designed by the Moving Picture Experts Group as part of its MPEG-1 standard. The group was formed by several teams of engineers at Fraunhofer IIS in Erlangen, Germany, AT&T-Bell Labs in Murray Hill, NJ, USA, Thomson-Brandt, and CCETT as well as others. It was approved as an ISO/IEC standard in 1991.
The use in MP3 of a lossy compression algorithm is designed to greatly reduce the amount of data required to represent the audio recording and still sound like a faithful reproduction of the original uncompressed audio for most listeners. An MP3 file that is created using the setting of 128 kbit/s will result in a file that is about 1/11th the size of the CD file created from the original audio source. An MP3 file can also be constructed at higher or lower bit rates, with higher or lower resulting quality. The compression works by reducing accuracy of certain parts of sound that are deemed beyond the auditory resolution ability of most people. This method is commonly referred to as perceptual coding. It internally provides a representation of sound within a short-term time/frequency analysis window, by using psychoacoustic models to discard or reduce precision of components less audible to human hearing, and recording the remaining information in an efficient manner. This is relatively similar to the principles used by JPEG, an image compression format.
