Filename too long in Git for Windows

I'm using Git-1.9.0-preview20140217 for Windows. As I know, this release should fix the issue with too long filenames. But not for me.

Surely I'm doing something wrong: I did git config core.longpaths true and git add . and then git commit. Everything went well. But when I now do a git status, I get a list of files with Filename too long, for example:

node_modules/grunt-contrib-imagemin/node_modules/pngquant-bin/node_modules/bin-wrapper/node_modules/download/node_modules/request/node_modules/form-data/node_modules/combined-stream/node_modules/delayed-stream/test/integration/test-handle-source-errors.js: Filename too long

It is quite simple to reproduce for me: just create a Yeoman web application with the Angular generator ("yo angular") and remove node_modules from the .gitignore file. Then repeat the aforementioned Git commands.

What am I missing here?

Where do you read that that version should fix the long filenames?
Here is the pull request for the patch: github.com/msysgit/git/pull/122
@PapaMufflon can you change the accepted answer to the one with more score? It just helped me a lot.
@v.karbovnichy please read my question carefully. I already ran the command in the top voted answer. But at the time I asked the question, the accepted answer was correct: msys still had this character-limitation. Now that limitation is gone and git config core.longpaths true works like it should.
Ok, I agree then

Git has a limit of 4096 characters for a filename, except on Windows when Git is compiled with msys. It uses an older version of the Windows API and there's a limit of 260 characters for a filename.

So as far as I understand this, it's a limitation of msys and not of Git. You can read the details here: https://github.com/msysgit/git/pull/110

You can circumvent this by using another Git client on Windows or set core.longpaths to true as explained in other answers.

git config --system core.longpaths true

Git is build as a combination of scripts and compiled code. With the above change some of the scripts might fail. That's the reason for core.longpaths not to be enabled by default.

The windows documentation at https://docs.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=cmd#enable-long-paths-in-windows-10-version-1607-and-later has some more information:

Starting in Windows 10, version 1607, MAX_PATH limitations have been removed from common Win32 file and directory functions. However, you must opt-in to the new behavior. A registry key allows you to enable or disable the new long path behavior. To enable long path behavior set the registry key at HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled (Type: REG_DWORD)


The limitation to 260 chars in a path is not specific to MSYS, it's a general Windows API imitation. This can be worked around by using Unicode paths, but that has other drawbacks, which is why core.longpaths is not enabled by default. Also note that Git for Windows it not compiled against MSYS. Instead, it's a native Windows application that comes with a stripped-down MSYS environment.
@sschuberth: Are there any drawbacks other than lack of compatibility with programs that do not support long paths?
@JAB Another drawback is that long paths always have to be absolute; relative paths are not supported. For further details please see here.
Or as a quick fix, just try checkout your repo to C:/ on windows thus reducing number of folder path characters.
As of Windows 10, you can edit your registry (or apply a group policy) to remove the Windows API filename length restriction. howtogeek.com/266621/…

You should be able to run the command

git config --system core.longpaths true

or add it to one of your Git configuration files manually to turn this functionality on, once you are on a supported version of Git. It looks like maybe 1.9.0 and after.


This config option fixed the issue for me, even with msys as mentioned in the accepted answer. (Specifically, version 1.9.4.msysgit.2).
Sourcetree acts a bit weird unless you "also make sure that SourceTree is using the System’s Git and not the embedded one." - Thanks to Matej Drolc for that advice
Here is some background information why this is not enabled by default, and some technical details.
get "could not lock config file C:\Program Files\Git\mingw64/etc/gitconfig" after running command above. But @Yash answer worked for me
@divideByZero running git bash as administrator prevents that error.

This might help:

git config core.longpaths true

Basic explanation: This answer suggests not to have such setting applied to the global system (to all projects so avoiding --system or --global tag) configurations. This command only solves the problem by being specific to the current project.

EDIT:

This is an important answer related to the "permission denied" issue for those whom does not granted to change git settings globally.


Folks here have noted that this setting can introduce some unpredictable behavior so it seems that it's preferable to use the above command as a local setting on projects where that require it rather than appending --system which will apply it to all projects
hey, that's just a copypasta of the other highly upvoted answer. might at the very least explain why you prefer removing the --system option..
I didn't have elevated rights and thus this was much easier to do inside the git repository than to ask the IT team to run the global command with elevated rights. Thanks Sagiruddin!

Steps to follow (Windows):

Run Git Bash as administrator (right-clicking the app shortcut will show the option to Run as Administrator ) Run the following command:

git config --system core.longpaths true

Note: if step 2 does not work or gives any error, you can also try running this command:

git config --global core.longpaths true

git config --global core.longpaths true saved my day. Thank you

Create .gitconfig and add

[core]
longpaths = true

You can create the file in a project location (not sure) and also in the global location. In my case the location is C:\Users\{name}\.


You can also do this with the following command: git config --global core.longpaths true
git config --global core.longpaths true worked for me thanks
Using Visual Studio the git bash solutions above did not work for me, but finding the .git/config file for the project and editing as shown above did. Thanks yash.
this worked for me, i located that file and modified it manually
The above mentioned and verified answers are correct but with the permissions which is granted to the file, it might not be possible to update the file with those commands. This approach is really easy because this is the manual approach and it worked for me really well. You can easily find the .gitconfig file in the following path C:\Users\{username} and simply edit it.

To be entirely sure that it takes effect immediately after the repository is initialized, but before the remote history is fetched or any files checked out, it is safer to use it this way:

git clone -c core.longpaths=true <repo-url>

-c key=value Set a configuration variable in the newly-created repository; this takes effect immediately after the repository is initialized, but before the remote history is fetched or any files checked out. The key is in the same format as expected by git-config1 (e.g., core.eol=true). If multiple values are given for the same key, each value will be written to the config file. This makes it safe, for example, to add additional fetch refspecs to the origin remote.

The better solution is enable the longpath parameter from Git.

git config --system core.longpaths true

But a workaround that works is remove the node_modules folder from Git:

$ git rm -r --cached node_modules
$ vi .gitignore

Add node_modules in a new row inside the .gitignore file. After doing this, push your modifications:

$ git add .gitignore
$ git commit -m "node_modules removed"
$ git push

There's a good reason to keep the node_modules folder checked into git: If you want your software to behave the same after a year of modules potentially vanishing from npm.
@cfstras if some library has a vulnerabily and you don't update periodically, certainly you'll have security problems.
Of course you have to upgrade your dependencies. But only when you want to, and if something were to break, you would want your backup in git...
Is true. I'll edit my anwser. Thank you for you comment.
No need to commit node_modules: the packages.lockfile is here to ensure the version installed by npm installwill always be the same, until you make a npm update

Executing git config --system core.longpaths true thrown an error to me:

"error: could not lock config file C:\Program Files (x86)\Git\mingw32/etc/gitconfig: Permission denied"

Fixed with executing the command at the global level:

git config --global core.longpaths true

The global settings affect only the current user, whereas system settings affect all the users on the machine. If this is your workstation they're effectively the same as you may use only one user.
If you're command line application Ran as Administrator, first command would work!

This worked for me

https://i.stack.imgur.com/YD4se.png

Run as terminal as administrator. And run the command below.

git config --system core.longpaths true

amalik2205
git config --global core.longpaths true

The above command worked for me. Using '--system' gave me config file not locked error


for Github Desktop users, this is the only one that works because Github Desktop uses its own Git config.

You could also try to enable long file paths.

If you run Windows 10 Home Edition you could change your Registry to enable long paths.

Go to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem in regedit and then set LongPathsEnabled to 1.

If you have Windows 10 Pro or Enterprise you could also use Local Group Policies.

Go to Computer ConfigurationAdministrative TemplatesSystemFilesystem in gpedit.msc, open Enable Win32 long paths and set it to Enabled.


I believe this must be done in combination with the git config, and it's worth noting it doesn't work with Windows Explorer for the reasons mentioned here.
Win32 - I wonder if this can help if the application is 64bit?

Download & Install Git bash from here: https://git-scm.com/download/win

Run the git bash gui as administrator and run this command: git config --system core.longpaths true

Now clone any repository.

If the problem is not fixed try this command: git config --global core.longpaths true

If it does not help try restarting the windows.

TortoiseGit (Windows)

For anyone using TortoiseGit for Windows, I did this:

(1) Right-click on the folder containing your project. Select TortoiseGit -> Settings.

(2) On the "Git" tab, click the button to "Edit local .git/config".

(3) In the text file that pops up, under the [core] section, add: longpaths = true

I hope this minimizes any possible system-wide issues, since we are not editing the global .gitconfig file, but rather just the one for this particular repository.

Move repository to root of your drive (temporary fix)

You can try to temporarily move the local repository (the entire folder) to the root of your drive or as close to the root as possible.

Since the path is smaller at the root of the drive, it sometimes fixes the issues.

On Windows, I'd move this to C:\ or another drive's root.


This is the only thing that solved my issue. It was that I had too many folders in the path.

In Windows, you can follow these steps which worked for me.

Open your cmd or git bash as an administrator

Give the following command either from cmd or git bash which you ran above as an administrator

git config --system core.longpaths true

This will allow accessing long paths globally And now you can clone the repository with no issues with long paths

I had this error too, but in my case the cause was using an outdated version of npm, v1.4.28.

Updating to npm v3 followed by

rm -rf node_modules
npm -i

worked for me. npm issue 2697 has details of the "maximally flat" folder structure included in npm v3 (released 2015-06-25).

If you are working with your encrypted partition, consider moving the folder to an unencrypted partition, for example a /tmp, running git pull, and then moving back.
