I have an issue with CCleaner and Free Download Manager. It seems after I clean my system, my custom user folder settings are deleted from Free Download Manager. I'd like to get to the bottom of this and find exactly which files I need to exclude in order to prevent this from happening as I have to reconfigure folder settings in FDM after every clean. Does anyone else use FDM and has encountered/fixed this problem? For additional info, these are the settings I clean with in CC. Dan
