Unlocker v1.5.1 released
Unlocker v1.5.1 released [freeware]

Unlocker is an explorer extension that allows you with a simple right-click of the mouse on a file or folder to get rid of error message such as error deleting file or folder, cannot delete folder: it is used by another person or program.

System requirements:
Windows 2000/XP




baatazu 05-07-2005 14:54

Doesnt work for me. I have an EXE running and I tried to delete it while its running. I got the Access Denied msg. So I tried using Unlocker and it says:

Unlocker 1.5.1
No locking handle found

Windows XP Pro English.

k2k2000 05-08-2005 08:50

this prog is for delleting ,files and folders used by running program.
not to delete the running program itself

MaRKuS-DJM 05-08-2005 22:02

btw, why do you want to delete running programs?

baatazu 05-09-2005 02:39

I have a program that runs remotely from a server to 50 to 120 pcs. When I want to update the software I have to wait when nobody's running the prog. I couldnt find a way/util to overwrite the exe because its already in use. The only way is to reboot the server and then I can put the new exe. Do you have any good idea for that?

ricnar456 05-09-2005 05:48

works perfect for me, i have a file impossible to delete (always is in use and never program are using really) and with this program i can delete easily.


Lana 05-09-2005 07:29

This works great, before I used an app called, Gipo@FileUtilities, but it required me to reboot in order to delete a locked file...but this can do it immediately for me. =)

Andromeda 05-09-2005 10:47

Yes, I need this program, too. Thank's, Lana.
Sometimes, when working with so many program, file(s) or folder(s) can't delete with warning "used by another program", which actually already closed. I hate those situation, and most of them I restart the computer. This one is time saving! Appreciated the info...

1.5.2 released


k2k2000 05-10-2005 19:29

version 1.6

# Change Log

Unlocker 1.6 - 09/05/2005

- DLLs locked by processes are now listed
- DLLs locked by processes can be unloaded. This make of Unlocker a very useful tool against viruses, trojan and worms that attach DLLs to processes to be invisible. Again I strongly advise to be extremely careful with this functionnality
- Window position and columns sizes are now remembered by Unlocker. Thanks to Michael for the suggestion
- Hovering tooltip displayed when content do not fit in a column. Thanks to Michael for the suggestion
- Changed back to MEW since WinUPack is wrongfully detected as a virus by poor anti-viruses such as McAfee. Unlocker will never contain any virus and it is a shame that McAfee is not able to unpack files packed with WinUPack, and properly unacceptable for a professional tool. Generally speaking if you have any doubt about a file you can submit a file to be scanned by several anti-viruses Virus Total and Jotti VirusScan. Those sites do not install anything on your machine, you just submit a file to them and they scan it by over 13 different anti-viruses. Thanks to all users who had problems for their support

Not a lot you can do in this situation.. programs that feature auto-update functionality do so in a staged (2 step) way. First, DL new version, then updater exe tells old version (or itself, if update is self-contained) to exit, updates it, then re-runs external app to restart app.

Maybe you can just do the ol' rename trick, provided you have the replacement exe handy? rename current -> old, new -> current ..


ILCH 05-11-2005 04:41

Great Tool !!!

Works perfect for me !!!

v1.61 is Out
Unlocker 1.6.1 - 10/05/2005

- Filtered modules locked by processes to only list DLLs
- Unlocker.exe is not packed anymore. Since even MEW was reported as a false positives with poor products such as Norman anti-virus and BOClean anti-trojan. Sad but true

Full history see here:


NeOXOeN 05-11-2005 05:22

NEw Version Out:

Unlocker 1.6.6 - 11/07/2005

- Added option to move/rename the object Unlocked instead of just deleting it. Thanks to Michael for the suggestion
- Fixed a bug which could cause a reboot. Thanks to Khadhrawi Mohammad for his help while debugging
- Fixed a slown down during the parsing of all system handles. Unlocker should now be as fast as versions prior to 1.6.3 since the slowdown appeared in 1.6.3

This can be turned off during the installation in the components section. This will require Unlocker to connect to the internet every time it checks for a new version. For those curious Unlocker is only sending "GET /unlocker/version.txt HTTP/1.0\r\nHost: ccollomb.free.fr\r\n" and nothing else. Thanks to Jean-Paul Chavant and Osman Zeki for the suggestion.

Unlocker 1.6.4 - 15/06/2005

Thanks to Takahiko Nishio and Taeko Tanaka both from the Windows 100% Japanese magazine for the Japanese translation. French translation done by me since I am French :)

- Added a tab-stop on the handles list. Thanks to Michael D. Lawler for the suggestion
- Added a check-box to delete file or folder after unlocking its handles
- Added a button to kill processes when unlocking handles is not enough to delete a file such as C:\Documents and Settings\username\Cookies\index.dat
- Fixed a bug causing Unlocker to hang when a DLL can not be Unloaded such as wininet.dll for example

As stevematulis said, renaming the current file should work. However, in my experience, this doesn't always work, and I haven't been able to determine the difference in cases when it works and when it doesn't. I used this trick in a commercial software that needed to update files on remote nodes. The last time I checked (several years ago), MSI used the same trick, and I noticed that it also dealth with these two cases. When renaming didn't work, it marked files for move on next reboot.
