File

From Nikonians Wiki

Computer information is organised into files, where each file is a document, application, or some type of supporting file. Files are kept in folders or directories, which are held on drives.

• Document files include word-processing files, such as Microsoft Word's .DOC, or image files such as JPEG, TIFF and NEF, or audio files such as MP3, WAV and AIFF, or a variety of other types.
• Application files including applications such as Photoshop
• Supporting files include Windows dynamic link libraries, .dll, and Macintosh library files. Supporting files are usually kept in folders not normally accessed by the user

• On Windows and other MS DOS based systems, all files have a three letter suffix which determines the file type, such as .JPG. This tells the system what kind of file it is.
• On Linux and other UNIX systems, which are very common as web servers, the suffix does not have to be three letters, and, for web files, is often four letters, such as .HTML or .JPEG. This can create problems for Windows users bringing files across from the web.
• On the Macintosh, the file type is implicit within the file itself, and no suffix is necessary. However, many Macintosh applications add a three letter suffix to maintain compatibility with Windows users.
