Cannot delete a certain folder in XP or Vista? You have an error message saying, “Cannot delete file. It is being used by another person or program,” I assume. Well, the error message have explained it accurately.
Personally, I think that Microsoft has deliberately imposed this windows limitation to protect us from ourselves, it is not safe to delete files that may be necessary for your system’s stability. However, this is not always the case. In fact, some viruses exploit this Microsoft security feature and turn this against us. This feature would then make viruses undeletable.
So how do we delete undeletable files or folders?
The answer is unlocker. Unlocker is a free software developed by Cedrick Collomb to easily delete locked or undeletable folders or files. This application is compatible with Windows 200, 2003, XP and Vista operating systems.
Instructions:
- Download and Install Unlocker.
- After installing you can access the tool by right clicking on the folder or file that you wish to delete and click on the unlocker wand.
Disclaimer:
Deleting needed files or folders can damage other applications or worst cause boot problems in your computer. Use this program at your own risk.


UNlocker is getting old. Its dated early 2008 June.
It doesn’t work on 64bit OS nor in Windows7. We need another solution. I’m stuck with an undeletable folder with two files: flash10b and flashutil10b, both executables, I tried everything known so far: renaming, going in DOS, Process explorer, unlocker etc. Every single software known in google.
Tried to take ownership and when I click on delete, it says I need permission from my own account. In which I’m logged in
flash10b and flashutil10b.. This is for your flash player 10. Why would you wanna delete it anyway? You can just ” replace it or repair it” by downloading and installing adobe flash player 10..
Anyway, if you still want to delete it try the following software alternatives it may work in your system, let me know which one worked!.

Please do not be so sure of yourselves, especially you Sergii. That did not work….lol .. i am with 8of7. NOTHING has worked. Mine were in an old windows directory on another partition. created while trialling x64 x86 bit win7 systems. I cannot rid myself of these files even when i try to do these procedures from safe mode. Someone out here must know a solution that encompasses above the simplistic we are continually given.
Cheers
and happy new year.
I love it!
