Hi, I have suddenly ran out of hard drive space on my 100Gb PB hard drive. There hasn't been any more large files added to my PB, but all of a sudden my space has vanished. I'm missing around 10-20Gb of space. I know that the virtual memory files (or paging files?) can sometimes do this, but you cannot just delete them as OS X is supposed to handle them on its own. It doesn't seem to be doing this so does anyone know how to manually and safely delete these files and free up my space? Also...am I on the right lines with the virtual memory?? It is a heavily used machine for work and uni use, but did have around 20Gb free not long ago and I have not put that much stuff on it! I've gone through everything to try and delete stuff I don't need but I'm pretty streamlined, but still have no drive space left! Thanks for any insight and advice!
