# How to delete a file with a path too long to be deleted [duplicate]

I was working with some computer vision source code I found and didn't realize that it creates a cache file that has a VERY LONG name and now I can't delete the 2 of them.

I tried to rename it to a shorter name but I can't do anything to the file, I also tried to restart my computer and see if it would just go away.

The error message says:

Destination Path Too Long.

The file name(s) would be too long for the destination folder. You can shorten file name and try again, or try a location that has a shorter path.

How can I delete the files in this case?

Would it work from the command line with the del command? Something along the lines of del *.cache should delete all .cache files in the current directory. – Ryan May 16 '14 at 20:14
"Path\to\folder\CACHEI~ The system could not find the file specified" said that twice and there's 2 files in there but didn't do anything – Duck May 16 '14 at 20:17
On second thought, you could check one of the other questions that has already been answered. This one for example. – Ryan May 16 '14 at 20:18
If these two files are the only ones left in the directory, then you may have better luck deleting the entire directory. From the command prompt, try rd /s directoryname This will wipe out directoryname and all files/subdirectories within it, so use it with caution :) – bitsmack May 16 '14 at 20:22

Assuming you are on windows:

What I always do is use subst to create a driveletter asccociation with part of the path.

Then go to the new driveletter and navigate to the files that have long names. You should now be able to rename/delete/etc them. The reason this works is because the path itself is no longer containing >255 chars.

# To create a subst folder

1. Start a commandprompt (no admin privileges needed)
2. Use cd to navigate to the folder you want to go (you can use tab to autocomplete names
3. type subst j: . to create the driveletter association. (instead of the . you can also type the entire path)
4. Now in explorer you have a new letter. Go to it and do whatever you need to do to the .cache files.
5. Go back to your cmd window and type subst /d j: to remove the drive or alternatively, restart your pc.

EDIT: A trick I learned which can shorten this quite a bit. From the explorer window where you have trouble, click the addressbar so you can type in it, then type cmd and press Enter to start a command prompt at that location, then proceed at step 3. :)

EDIT2: Okay, this trick can be expanded even further. If you are in explorer at the right path, just type in subst j: . in the addressbar and press enter. A command window will pop up, execute the command and close again, and there you go, a new drive pops up in explorer.

thank you so much! that worked – Duck May 16 '14 at 20:24
Wow Microsoft. Wow. – SgtPooki Sep 25 '14 at 19:52

Just tried this and i could not remove the file in question.. I use cygwin with windows, an alternative solution is to remove the file that way: rm -R /path/in/question as long as no other program is using the file you are good to go – John Mar 3 '15 at 17:28
I had an issue where SUBST didn't recognise J: as a parameter (it also didn't see any virtual drives that were available) so the cygwin option mentioned by John worked well. – Tisch Apr 1 '15 at 12:40

Your question asks how to delete a file when the filename itself is too long. If the path is too long and not just the filename itself, you can easily just rename the folders to make the path shorter.

But to delete a file whose name is more than 255 characters:

• Open a command prompt by running "CMD.EXE"
• Navigate to the folder holding the file
• Use the command DIR /X which will display the short names of files.
• Delete using the short name.

i.e. if the file is named "verylongfilename.fil", the shortname will display as something like "verylo~1.fil" and you can delete using that name.

Please note that although Windows itself can handle paths far longer than 255 characters, most of the GUI -- like Windows Explorer -- is bound by the shorter limit.

This is a better answer than the accepted on. – Ben Jan 16 '15 at 21:06
Far better answer, thank you! – Steffen Müller Jan 26 '15 at 12:54

The chosen answer is better because you can delete whole folders with that method – Matteo May 28 '15 at 19:08

Googled: delete long filename First result

Cannot delete folder: It is being used by another person or program Cannot delete file: Access is denied There has been a sharing violation. The source or destination file may be in use. The file is in use by another program or user. Make sure the disk is not full or write-protected and that the file is not currently in use.

Unlocker can help! Simply right-click the folder or file and select Unlocker. If the folder or file is locked, a window listing of lockers will appear. Simply click Unlock All and you are done!

I did see that but didn't know if unblocker was safe to use so I ignored it, I'll try it out. EDIT: didn't work. it works on other files but unblocker doesn't appear in the drop down – Duck May 16 '14 at 20:20
Certainly the simplest way to do it, although it may need a reboot to complete. Nothing wrong with Unlocker at all - been using it for years and it's a very useful utility. In the case of a file or folder whose path is too long it will find no locking handle but should offer the Delete option in the drop down afterwards. – Steve Pettifer Jan 12 '15 at 14:55
Worked flawlessly - funny thing is I have this software installed but didn't occurred to me to use it in this situation. – Daniel Sokolowski Jan 3 at 1:27
Didn't work for another folder where I copied a circular junction folder, but what did work was renaming each level folder to one character like 1 all the way and then deleting it. – Daniel Sokolowski Jan 3 at 1:39

Microsoft has a useful knowledge base article on deleting undeletable files. Cause #4 is of relevance to you.

Your best bet would probably be to map a drive to the folder that file is in (resolution #3), then enter in through that drive and delete it.
