No i dont have this problem, but i thought it would be nice to for example schedule a file for deletion on next boot. I was thinking on basicly all files, not just .dat.
The "options-custom-add file" only removes the selected file, not on the next boot, ans so it won't remove files that are in use. (viruses, exe-files, some media files etc)
I agree the kill prosess thing, is a bit out of order, but you could for example use it to kill the prosess using the file, if youre too lazy pressing "ctrl+alt+del". We like all in one programs:P
But serious the schedule file thingy, could be a nice feature.
