Why are my xlsx files locked for editing? Last week they opened just fine. Today, 3 of the 8 files in the same folder will only open as Read Only.
Issue started today when I tried to open a few xlsx files. There are 8 files in the same folder but only 3 are giving me this problem (I had those 3 opened last week and had no issues). I get the message "File is Locked for Editing" and gives me the option to cancel or open Read Only. I opened RO and after several seconds another pop up says the file "is available. do you want to edit it now?" I click on Edit and the original message of it being locked for editing pops up. Vicious cycle.
So I renamed the file and saved it to my desktop. I then command-delete the original, then copied the newly named file to the folder (after first opening from the desktop to verify all was good. It was). I opened the new file and it opened ok. After closing I renamed it to the original file name and lo and behold got the same errors again. Vicious cycle continues.
I've restarted but it hasn't corrected the issue. Would appreciate a solution if anyone has one. I've read about hidden files and such but have no idea where to even look. This all started today after a cold start up.
OS X is El Capitan 10.11.3. I run MS Office for MAC and Word files opened w/o issue as do other xlsx files. I've deleted my recent items list but nothing works.
