I just started editing video at my DZ and have run into a memory issue. I have found the Sony Vegas 10.0 file that is currently 309 gigs, but this appears to be the where the final edits are saved. We use Production Assistant 2.0 and have the "Copy source files to project folder" as well as "Keep parent folder at destination" checked. I would like to know what files I can safely delete, as it appears that there are some double copies with the current set up.
