I use a program called Sony AcidPro a lot and it creates .sfk files which are only needed while running the program. The files aren't written to a specific folder, instead into every folder where music loops which have been used are located. Once the program is closed the files are no longer needed, (but remain) as they're written again when the program is reopened. I've tried to select custom files to delete in CCleaner, input *.sfk as a custom file, but CCleaner only gives an option to open the file. How can I add *.sfk files to be deleted in CCleaner? It would be a great way to clean out these un-needed files along with everything else CCleaner deletes instead of using the Windows search function to find .sfk files, then deleting them.
