So I convert the MOV files with NeoScene. Once the conversion is finished, and I've played around with the avi files, I try to delete everything. It will delete the avi files, but not the MOV files. It says the files are still being used by some program. NeoScene is the only program that touches these files. Neoscene is NOT on or using them.

So...what am I doing wrong?

I found an app (I had it long ago but forgot about it) that unlocks or kills the connection between the file and whatever app it's being used by. It's called unlocker 1.8.7

Still, it would be nice to know why my files are not just deleting.
