Windows 10: Destination path too long after enable NTFS long path

I have windows pro 10 education and 1903 version. I enable NFTS long path and update the group policy with this command:

gpupdate /target:computer /force


But when I copy-paste folders to an external drive I still get the error Destination path too long The file name(s) would be too long for the destination folder. You can shorten the file name and try again, or try a location that has a shorter path.


Thanks in advance.

Destination path too long

Hi,

Long paths works for NTFS file system only.

https://docs.microsoft.com/en-us/windows/win32/...

Enable Long Paths in Windows 10, Version 1607, and Later

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.

To enable the new long path behavior, both of the following conditions must be met:

The registry key HKLM\SYSTEM\CurrentControlSet\Control\FileSystem LongPathsEnabled (Type: REG_DWORD) must exist and be set to 1. The key's value will be cached by the system (per process) after the first call to an affected Win32 file or directory function
(see below for the list of functions). The registry key will not be reloaded during the lifetime of the process. In order for all apps on the system to recognize the value of the key, a reboot might be required because some processes may have started before
the key was set.

Note

This registry key can also be controlled via Group Policy at Computer Configuration > Administrative Templates > System > Filesystem > Enable NTFS long paths.

If you wish to utilize this feature, however, you will be required to make some edits to using Group Policy. Follow the steps below:

Open Group Policy Editor (Press Windows Key and type gpedit.msc and hit Enter key.

Navigate to the following directory: Local Computer Policy > Computer Configuration > Administrative Templates > System > Filesystem > NTFS.

Click Enable NTFS long paths option and enable it.

Regards,

Lee

GPO: enable win32 long paths

I saw that the Windows 10 Anniversary Update was supposed to address the limitation of long file paths and names. According to what I found, the new GPO entry of "enable NTFS long paths" was supposed to be added, but I didn't see it. Upon further research,
I did find the "enable win32 long paths" option one level up in the GPO.

Question: Was this supposed to address the problem? After I enabled it, rebooted the computer and confirmed that the setting was still enabled, I tried to copy a file (via File Explorer) from a local hard drive (G:\*.*) to a server share (\\SERVER\SHARE),
but it failed for the same old reason that the pathname was too long. Does this only work locally, or does it only work with specific capabilities, like PowerShell?

 

Long Path Setting not working

Seems Enabling Win32 long path to overcome the 260 character restriction has not yet resolved the issue. I have enabled Win32 long path under group policy editor--> Filesystem and also the reg key D word setting but continue to receive error " The file
name would be too ling for the destination folder....."
