I have a few feature suggestions for CCleaner. At the moment, there is an option in CCleaner to erase custom files/folders, but this only occurs when you run the whole CCleaner process (unless you deselect everything else and only have the custom files to be erased).
Would it be possible to have an option to erase individual files/folders in CCleaner, without doing the full CCleaner clean? This additional function could be located in the 'tools' section below 'Drive Wiper'. It could be a list where you add single files/folders to erase (with drag and drop functionality, and/or a browse button) and a button at the bottom that says 'Erase' that will erase all the items on the list.
There could also be a right click context menu added, that will enable you to erase the selected files/folders that way as well.
In My Computer, you could right click on a drive, and have an option to Erase Freespace, and Wipe drive as well.
Second, I believe the 'single pass' method used in CCleaner overwrites the files with a single pass of zeros. Would it be possible to have an option to have a single pass of random data also?
And third, would it be possible to add custom registry keys to the 'Include' section. This would enable advanced users to clean applications that might not currently be supported by CCleaner.
