Show file extensions in File Explorer

Microsoft hides file extensions by default, which makes life difficult for people who need to look for specific types of files, like JPEGs and JPGs. To see file extensions in File Explorer, do the following:

1. Using Search in the task bar, and type File Explorer Options, and click it. (There are other ways to get here too, such as using search in the Start menu, but this method works fine.)

2. In the window that pops up, click the View tab.

3. If it’s checked, uncheck the box that says Hide extensions for known file types. Click Apply, and OK. You should now see file extensions for all files in the File Explorer.

You can also use the File Explorer Options menu to choose to show empty drives, hidden files and folders, and more.
