Any error messages?
How are you trying to move these files?
If you attempt to 'drag and drop' files from one hard disk to another, (whether external or internal), Vista will automatically assume you want to copy, and not Cut/Paste.
When I want to do this I just select all the files, cut, then paste in the new location. But I don't do that often. If I cut, then the system fails in anyway then I risk losing all those files, so I use the method you are using, copy, paste, then delete the ones I just copied from.
I have Vista Home Premium on my laptop. I have alot of pics that I want to move to an external drive, but Vista will only let me "copy" them. Then I have to delete the original. This takes too much time. How can I get Vista to let me "move" the pics, instead of just copying them? Or is there a free or cheap program I can use to "move" my pics? Any recommendations will be greatly appreciated. I use to use Powerdesk with XP, but it causes crashes in Vista.
