I had a folder which was about 2.8GB. I compressed it to zip format using the command from the file menu. It is now 2.5GB, but refuses to finish unzipping. At about 75% complete it says that it can't open it because it is damaged. Now when I compressed that folder, I compressed a other folder 20 minutes before. It is 1.5GB in size and unzips perfectly! Why is the larger file not working? And yes I tried Stuffit Deluxe and Terminal and both don't work. Does anyone know of any other ideas?
