File Extensions -

File extensions are the three letters that come after the dot in a file name.

For example, a setup program might be called something like setup.exe. The ".exe" is the file extension.

Extensions are used to let the computer know what type of file it's dealing with. For example, if it's a ".jpg" file, the computer knows it's an image file.

If it's an ".exe" file, the computer knows it's a program.

It's important not to change file extensions unless you have a compelling reason to do so.

Changing the extension can (and usually do) make the file unusable.
