Been having this problem for a couple years now....I can create zipped folders just fine and I can open zipped folders just fine.
But when I zip one up and send it to someone else they cannot get the zipped folder to unzip.
I know this happens when the other person is on a Mac, and I've had people with PC's encounter the same problem. Am I the only one? Hopefully not! Any thoughts on how to remedy this?
You were right (again), thank you. I un-checked the box in Zip Files settings area for super-duper deluxe compression, tested it on a friend of mine with known, antiquated, software tools (prior problems with this issue) and she was able to open it. TYVM!
