Hello everyone, I'm running Tiger 11 on an ibook g4 with 27GB of memory. I find I don't have enough memory even to keep any music on it; the longer the computer goes without a restart the less hard drive space I have. I have never used more than about 8-9 GB for my own files, but until I deleted my music I frequently found that the computer had 'zero KB available' meaning that I couldn't even save changes to documents to my hard drive. When I restart I magically gain a GB or 2. Is this normal? How much hard drive should be available for personal use on a 27GB hard drive running Tiger? I've run an app called 'what size' and it says that 'previous systems' folders take up 5.69 GB. What do those folders do and is it necessary to keep them? I could kind of use the extra space. Also 'sampler' for garageband takes up 1.35 GB. If I deleted that would Garageband still run OK? I'm guessing not but I'm just wondering whether they're simply demos? Sorry for all the questions but my computer is being a bit annoying here! Hope you can help.
