Hi Kansas, I've had to do a lot of this lately with a number of designers. What I've been doing is first rebooting as has been mentioned. This helps clean up any swap files. I then turn on "Calculate Folder Sizes" for the Startup drive and do the sums on the 4 main folders to make sure that they tally correct. You can also turn down folders (in list view) to see what is taking up room. This helps you to determine if there's wasted stuff you don't want or if you do indeed have a discrepancy in what should be available and what IS available. I Get Info on the Startup to see what it says its total capacity is and what it thinks it is using. If the sums of the folders tally to 4GB and it says it is using 6GB then you know you have 2GB worth of invisible stuff to get rid of. BTW, make sure you check the Trash folder too... that has caught me out a few times. I then use Tinkertool to make all invisibles visible. With "calculate folders" still on you can click on the size column so all the biggest stuff rises to the top. I've found that stuff collects inside the Private/tmp folder. There are a few others that I've cleaned out some very large temp files from but I don't remember what they were... they were glaringly obvious at the time. Of course don't just start deleting hidden stuff willy-nilly or you may find it's the last time you boot up successfully. Anyway, that may help. Cheers, Cojcolds Kansas Territory <kansast at mac.com> Unfortunately, my OSX partition is about 10GB and I"m currently using up about 8GB and I"m wanting to install iLife 05, which requires about 4GB.. if I want to install everything. I'm trying to figure out what the heck is taking up 8GB in the first place ? my iTunes library is stored on an external Firewire drive. Also, my iPhoto library is stored on an external Firewire drive. I've gone thought my files etc in my home directory. It's not like i got much going on in that directory. any suggestions where I might could look ? figure out what's takin' up so much room ? OR is there a way. that when I go to install iLife 05.. could I maybe just install Garage Band on another drive other than my main OSX partition ? Because it seems like a good bit of this 4GB that is needed to install, is on account of Garage Band. Any suggestions would be appreciated. Kanasa
