I kept wondering why my C: drive kept losing space. I was saving nothing to it and kept deleting stuff or moving to D: drive as it was so into the red and kept losing free space. On this 150G drive, only a couple hundered meg were left.
Finally I discovered that deeply buried was a camera raw cache with 87G of files. As I thought I had changed the destination for this to the D: drive, long ago, I looked there and found that there was a CR cache there also with about 49G, but most recent were files from 7/11/2011. On the C: drive the files were from that date to the present, so somehow it defaulted back to the C: drive.
I can't just add the CR C: files to the D: cache as there is only 85G free on this drive, so I would first have to delete or move files back to the C: drive. So if I move a few dozen gig at a time to the D: .. cache folder and then move some other files back to the C: so I'll have room for the rest, and then redirect the cache in Bridge back to the D: ... cache, this should work?
But what are all these files? What would be the result if I just deleted and started over? Would I lose all the editing done on the CR files?
