Using OSX 10.5.8 on a PowerPC G5. The main disk states I only have 1.8GB free, but I've used a few utilities to find out where the space is being taken up and I'm not seeing what's taking up so much space. I've tried Omni Disk Sweeper, Disk Inventory X and another one. I used Cocktail to clear temp files and caches and rebooted. The only things it tells me are that the users folder has 25.3GB taken up, Applicaitons is 8.5GB, library is 7.4GB and System is 3.7GB. That does not add up to 146.9GB. Can someone help?
