May I suggest that when listing found junk files we could select which ones should be excluded from deletion?
Rules from winapp could include useful files, for example, some unistallers have the "great" idea of naming its unistall info "unistall.log". If this file is deleted, uninstaller won't work!
This could be implemented by clicking on the desired file (uninstall.log) and with a contextual menu, exclude it from the list. Or you could put a checkbox on the left of each file... like in the registry cleaner
Also would be nice being able to open selected files with default editor/viewer
Thanks!
