These are particularly useful in determining the integrity of files after they are transferred over a communication channel. Hashes are even utilized by certain OS-level processes for their working.

The command processor of Windows OS (cmd.exe) provides the user with the ability to compute hashes on files/Directories via an utility command named Certutil.

A file extension is generally last few characters in File Name after period (“.”). Though it is not mandatory for file to have an extension at all (in case of extension-less files).
