Back when I used WordPerfect, which could ignore file extensions, I gave all my poems the extension .POM. Word can read these files, but only if I add the extension .DOC. I have more than a hundred .POM files--how do I batch-add the .DOC extension to make them all read .POM.DOC?
Or, failing that, just change all the POM extensions to DOC? (But I'd rather do it the first way, so I can tell they're poems at a glance.)

Haven't done such with File Explorer or the previous Windows Explorer but have done some group renaming using Total Commander and Free Commander, third-party file managers. MajorGeeks.Com - MajorGeeks
Download - Bulk Rename Utility
This powerful utility can add, delete or change file extensions
Are you comfortable with the command line?
You can use the rename command. Open a command line window, navigate to the directory where the files are located, and then:
ren *.pom *.pom.doc
Just tried a quick test on some .gif files, changing them to .gif.tst. Worked. No additional software required.
