Files encrypted in a folder - how to reverse it? I've been playing with a computer game (Kerbal Space Program, OS X 10.9.3) and recently found that I can no longer load saved games (missions). I contacted the tech support and all they could say is that the folder containing the saved game files is encrypted. What is more,  I can create a new game but once I quit, I can no longer load it. It seems that something keeps encrypting the files in that particular folder. Why is this happening and what can I do about it? How can I reverse the encryption?
It may be due to ACLs. You can clear the ACLs on the folder recursively with:

chmod -R -N /path/to/folder
