A file type helps us in identifying the type of content that is saved in the file. Linux supports seven different types of files. These file types are the Regular file, Directory file, Link file, Character special file, Block special file, Socket file, and Named pipe file.

How do I tell a file type in Linux?

To determine the file type in Linux, we can use the file command. This command runs three sets of tests: the filesystem test, magic number test, and language test. The first test that succeeds causes the file type to be printed. For example, if a file is a text file, it will be recognized as ASCII text.

How do I find the file format?

1. Open File Explorer; if you do not have an icon for this in the task bar; click Start, click Windows System, and then File Explorer.
2. Click the View tab in File Explorer.
