Close file handle windows

I was wondering if there is a command-line tool that allows me to close all file handles that are open under a specific folder. I have tried ProcessExplorer , Unlocker and similar tools, but they offer a GUI interface, and are not useful in a programming environment.

Unlocker does claim it gives you this ability:. MalwareByte's FileAssassin performs similar actions, and does support command-line usage, so you should be able to script it pretty easily. Thanks for this. We've been having some issues with open file handles causing git checkouts to fail within our Windows-based Jenkins jobs and this helped correct the problem handily. I'll throw out the basics of the technique:. Install Handle.

This allows us to define operations before the git plugin started reaching for potentially locked files. It appears to work nicely and definitely cuts down on spurious failures. I'll also note a couple gotchas I worked through:. If you're running your Jenkins agent as a service under the Local System context, this is problematic because you can't log in as that user and accept it by hand. When we tried running it from the Jenkins job, the process just hung waiting for user input and it took a few minutes to figure out why.

The Jenkins Batch step plugin executes batch code as if it were in a script rather than as a command line directive. Notice the escapes e. We use the following snippet to close file handle from users to our server.

You may be able to modify it for your use.

If you're using PSTools , this will force close all open files recursively:. This was unclear to me at first so I thought I'd point it out.

Doing so will result in a sharing violation. Skip to main content. This browser is no longer supported. Download Microsoft Edge More info.

The software is also freeware and it gets the job done just like the former one. The tool also features a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

This will allow us to use it to easily fix most unwanted file locks in a matter of seconds: we just have to search for the locked file, retrieve the process which is keeping the handle and close or kill it accordingly. In order to achieve such surgical result we need to get our hands to another great Sysinternals utility that goes by the name of Handle.

Handle is basically the console version of ProcessExplorer : think of it like a ProcessExplorer with command-line options instead of the GUI. This could make it less intuitive when we need to investigate our system, yet it has extremely powerful tools when it comes to fix the issues we found.

If everything goes correctly, you will fix your problem without killing the process and — more importantly — without having to reboot the system.
