Windows 11 PC
Hi - I chose "Make online-only" for all files backed up on Dropbox. Realized this was the wrong thing to do as it slowed everything way down. I since clicked and chose "Make available offline".
Now i cannot open any files on my PC at all. Error message: "Cannot open the file 'xyz' because the file format or file extension is not valid. Verify that the file has not been corrupted and that the file extension matches the format of the file".
Please help - i can't access anything at all!!
