I'm pretty new to this unattended stuff, I'm still waiting for sp2 to be released for my native language, but in the meanwhile I might as well start working on reg tweaks that I'm gonna add.. so this is my question, would I have to make a new reg-thingy for each of the filetypes i want to associate to daemon tools, the one you made is for .iso right? so If I wanted to make another one for .cue this is what I'd have to do [HKEY_CLASSES_ROOT\.cue] @="CDImage" [HKEY_CLASSES_ROOT\CDImage] "EditFlags"=dword:00000000 "AlwaysShowExt"="" "BrowserFlags"=dword:00000008 @="" [HKEY_CLASSES_ROOT\CDImage\shell] @="Open" [HKEY_CLASSES_ROOT\CDImage\shell\Open] [HKEY_CLASSES_ROOT\CDImage\shell\Open\command] @="\"C:\\Program Files\\D-Tools\\daemon.exe\" -mount 0,\"%1\"" or would it be enough to just make [HKEY_CLASSES_ROOT\.cue] @="CDImage" without the last part about CDImage since it was allready added for the .iso extension... I hope I make myself clear thanks in advance Daniel
