I recently tried to trim down a 100GB project. I had 8GB left on my harddrive, and the project manager said the final project would be 7GB, so I took the chance and started trimming.
Unfortunately, I ran out of diskspace during the trim, and the Project Manager aborted the action. Fair enough. However, when I checked my diskspace in finder, I only had 100MB free space. That means the temp file, that the project manager created while trimming the project, is still stored somewhere. But I have no idea where it is stored or what it is named.
I'm on a Mac 10.6.4, CS5.
Do you know where (or how) to look?
Where are your Scratch Disks located?
What was the Destination Folder, that you directed PrPro to archive your Project?
Note that performance of a HDD begins to decline at ~ 70% of capacity, and falls off sharply, as one fills the drive. It can also contribute to premature failure of the HDD. Sounds like it's time to get larger, or more HDD's.
Scratch disk is same as project, trimmed project folder was empty, and it's an imac, so upgrading the hdd is not that easy to do.
