In addition to file types, this site introduces you to many other ways to make everyday computing easier, such as compressing and decompressing files.

Data Storage

A file refers to data stored on a hard drive or other storage medium stored as a separate entity.

For example, a sales presentation can be saved as a file, as can a slide show or photo.

Typical features of files

1. The file always has a name.
