After a frustrating few hours trying to figure this out via Google as I wasn't sure this was a Woody's Lounge topic, decided to come here and try. This is the only place whose help I can understand!!
I inadvertently changed the default zip extension to an image viewer, Irfanview (hate the automatic check mark in the "always open with this extension box"!!). I have no idea how the zipped files used to open (what the extension was originally). They certainly won't open with the Irfanview program.
Can you tell me how to get back to whatever the extension used to be as I had no problem before?
Thanks for any suggestions!
