When I decompress a zip file on my Mac, the folder is nowhere to be found. Help! Normally when I open a zip file, the contents immediately open up in the form of a decompressed folder. For some reason, the unzipping process appears to be happening but then nothing opens. Any experience with this?
also - around the same time, I've started noticing that if I save something to my desktop, it's nowhere to be found.
