How to add extensions onto multiple files?
Hi,
an external drive I had failed but I managed to retrieve all what I had. Unfortunately all the file extensions were gone. It is not an issue of not seeing them, they just disappeared (if I go to 'Get info' where it says 'Hide extension' is greyed out).
If I manually insert an extension to a file, the file opens without a problem. Unfortunately, I have a lot of file I need to access and manually adding an extension to each file is really time-consuming.
I know in Automator you can replace an extension, but I can't see that adding an extension is possible... Am I missing something? or is any other way to do it faster?
Thanks in advance for your help
