(Please forgive me if this is a repeat; I can't find the post I made earlier today on this.)
I am using MSPlat 15. After a recent W7 reinstall, data restoration from a backup, and re-installation of programs, my C drive is almost twice as full as it was when I took the machine to the shop. One big chunk of files, as revealed by Wiztree, is 34GB of avi files in C:\Users\(username)\AppData\Local\Sony\Movie Studio Platinum\12.0\Movie Studio Platinum Prerendered Video File, I haven't even been using v12 for nearly a year, nor do I see the real files -- pardon my lack of the technical term -- anywhere on my drive. Is there a way to view these? Can I safely delete them? Are there associated files I should delete as well? (The are 253 files in this folder, about 30 of which are these prerendered, and a couple of wave and .avi.) Will they go away if I uninstall v.12?
