Hi, It depends on the type of file you are trying to move. However, usually I find that it's a .dll file from a program I'm deleting that I have this problem with.
If this is YOUR case ... I am presuming that you do have your folders set so you can see file extensions i.e. their last name so to speak. If not...,
A: open control panel
B: open Folder Options
C: Click on the View Tab
D: Scroll down till you find the line "Hide extensions for known file types"
E: UNCHECK this box.
If you can see extensions skip the previous section. Going on...
I get around the system by:
1. Change the .dll extension to something else like .bak
2. reboot the system
3. Move the file (or in my case delete the file) to it's new system.
4. Your case ... change the .bak extension back to it's original .dll extension. (or whatever it really is in YOUR case)
5. Reboot your other system with the newly installed file.
6. Test the program with the file. (Hopefully it did not need to be registered in the Registry.)
7. DONE.
Hope this helps.
