Enabling Long File Path Support on Windows Server 2016

Question

Struggling to enable long file path support on Windows Server 2016. Group Policy and local policy have been configured according to the guidance, and the server has been rebooted. However, files or folders with paths exceeding 260 characters still cannot be accessed.

Answer 1

1. Verify Group Policy Settings:
   • Open the Group Policy Editor (gpedit.msc).
   • Navigate to Computer Configuration > Administrative Templates > System > Filesystem.
   • Ensure that the policy Enable Win32 long paths is set to Enabled.
2. Check the Registry Setting:
   • Open the Registry Editor (regedit).
   • Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem.
   • Ensure that the LongPathsEnabled DWORD value is set to 1.
3. Run gpupdate:
   • Open Command Prompt as an administrator.
   • Run gpupdate /force to ensure the Group Policy settings are applied.
4. Reboot the Server:
   • Sometimes, a second reboot might be necessary to fully apply the changes.
5. Application Compatibility:
   • Ensure that the applications you are using support long paths. Some older applications might not handle long paths correctly even if the system supports them.

Answer 2

Does Windows File Explorer support the long path? I have verified the settings you mentioned above.
