What is File? |
A file is a collection of data stored in one unit, under a filename. This can be a document, a picture, an audio or video file, a library, an application, or other collection of data.
Documents include text files, such as a Word documents, RTF (Rich Text Format) documents, PDFs, Web pages, and others. Pictures include JPEGs, GIFs, BMPs, and layered image files, such as Photoshop documents (PSDs). Audio files include MP3s, AACs, WAVs, AIFs, and several others. Video files can be MPEG, MOV, WMV, or DV files, just to name a few.
A library file is a unit of data that is referenced by a specific program or the operating system itself. These include plug-ins, components, scripts, and many others. An application is a program, or executable file. Programs such as Microsoft Internet Explorer and Apple iTunes are both applications, but are also files.
Like files, folders have names. However, folders themselves do not store any data. Instead, they can hold many files, which store the actual data. |
