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?

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)

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 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.

Steps to follow (Windows):

1. Run Git Bash as administrator (right-clicking the app shortcut will show the option to Run as Administrator )
2. 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

Read more about git config here.

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}\.

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>

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.

More info

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

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

This worked for me

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

git config --system core.longpaths true

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 Configuration → Administrative Templates → System → Filesystem in gpedit.msc, open Enable Win32 long paths and set it to Enabled.

git config --global core.longpaths true

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

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

Save and close everything, then re-try your commit. For me, this worked.

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.

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

1. Open your cmd or git bash as an administrator

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

git config --system core.longpaths true

3. This will allow accessing long paths globally

4. And now you can clone the repository with no issues with long paths

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.

• 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.

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).

In a windows Machine

Run Command Prompt as administrator then run below command

> git config --system core.longpaths true

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.
