Delete Undeletable Files or Folders in Windows

Posted on March 12, 2010


I’m pretty sure that most of our readers have found a file that won’t delete and is giving them problems.  I’ve faced that problem.

I’m not sure why files or folders sometimes won’t let you delete them.  It can just happen.  It might be because it is infected with a virus, but this guide isn’t going to cover that scenario.  We are going to tell you how to delete those files that get hung up for whatever reason and just won’t go away.

Today, I’m going to show you how to delete that pesky little file.


FileAssassin is the best tool I’ve found that gets the job of removing an unresponsive  file or folder. It unlocks the file/folder that is giving you trouble, unloads modules, terminates the file process and then deletes it.

Let’s walk through the steps of how to complete that process I just mentioned.  Go download FileAssassin from this url.  After the installation is completed, launch FileAssassin.

You will see the FileAssassin window, shown below.  First, you need to locate the file or folder you want it to delete. You can either drag-and-drop the desired file/folder on its textbox or browse your computer to locate the file. Once located, you will have several options.

FileASSASSIN v1.06

The best option is to select Attempt FileAssassin’s method of file processing. Below this option, you have several check boxes.  Here is what each one does.

  • Unlock Locked File handles: If you feel that the file is locked in any way, use this to unlock.
  • Unload modules: FileAssassin will dive deeper into the file to check modules and unload them.
  • Terminate the file’s process: If you think that you should not delete the file; but terminate its process, check this.
  • Delete the file: That’s what we were talking about. To perform the action of deleting the file forever from your computer, check this.

Your final job is click the Execute button to execute your orders.

FileAssassin is a light weight and easy to use program that gets the job done quickly.  I really recommend it, but I am interested in what software you use to kill off undeletable files.  Let us know in the comments.
