GENERAL QUESTIONS ABOUT IDM FUNCTIONS AND PROBLEMS
I want to delete files from my hard drive as well when I delete them from IDM list. How can I do this?
IDM has delete from disk feature. Each time you try to delete a download from IDM list, you will see a dialog that asks if you want to delete an actual file from your disk as well.
If you do not see this dialog, please make sure that you use the latest version of IDM.
If this does not help, you need to to delete "bNShConfDelFrLstDlg" value (arrow 2 on the image) of "HKEY_CURRENT_USER\Software\DownloadManager" registry key (arrow 1 on the image). Please read here how to work with Windows Registry.
