Windows 11 Home Single Language | Long Path Option Enabled Via Reg Edit |

DGA · Dec 7, 2023

Hi. Please assist if possible. Reg Editor: Data Value 1. Long Path Enabled but I am still being barred > 259.

There is solution here:

Enable long paths on Win 11 Home

I need to enable long paths but my Win 11 Home edition does not have the group policy editor. Is there a way to enable this from the command line or install group policy editor on my machine?

superuser.com

You might need to reboot system for changes to take effect.
In any case applications which require long paths should give you an option during installment to enable it.

There's no guarantee that this will work with all applications, probably to remain backwards compatible with older operating systems, from the Super User answer:

The real problem 90% of the time is going to be getting applications to support it and not the file system. Programmers hardcode MAX_PATH (260 chars) into their code and have been doing so for many many years.

One of those characters will be the null-terminator which is why you're limited to 259 rather than the stated 260.

No did not work. I have VERY limited knowledge of this stuff so am not following all that well, so please forgive me. MS 365 apps being used

@DGA

@DGA
I don't have Office installed to test it, but there seems to be a registry setting specific for Office and Office 365:

Use long file names whenever possible

Checks/Unchecks the corresponding UI option.

Thanks Zebal, Let me go have a look see and I'll let you know.

zebal · Dec 7, 2023

@DGA
To test it simply open registry editor (not as Administrator)
Then find sub key:
HKEY_CURRENT_USER\software\policies\microsoft\office\16.0\common\internet
Under this key on the right find "donotuselongfilenames" value, double click it to open and set it's value to 1

If the value doesn't exist create a new one by right clicking on the key "internet" -> New -> REG_DWORD
Name it donotuselongfilenames and set it's value to 1, click OK and reboot system.

Nope, still not working.I dont think I am signed in as administrator but will go look

It's not issue if you're Administrator, what matters is to open it by simply left clicking because in that case HKEY_CURRENT_USER will apply to you rather than other user if there is one.

If this doesn't work even after reboot then IDK how to fix it, but this setting indicates there should be UI option in MS Office program, ex. excel.

x BlueRobot · Dec 7, 2023

Let's just double check that the registry keys have been created properly:

Code:

reg query HKEY_CURRENT_USER\software\policies\microsoft\office\16.0\common\internet /v donotuselongfilenames >> %userprofile%\Desktop\RegistryKeys.txt
reg query HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem /v LongPathsEnabled >> %userprofile%\Desktop\RegistryKeys.txt

Please attach the RegistryKeys.txt file which should be on your Desktop to your next post.

Alternatively, you can make sure they're set using:

Code:

reg add HKEY_CURRENT_USER\software\policies\microsoft\office\16.0\common\internet /v donotuselongfilenames /t REG_DWORD /d 0x1 /f
reg add HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem /v LongPathsEnabled /t REG_DWORD /d 0x1 /f

Otherwise, those applications have been hardcoded to use the shorter file paths in order to be backwards compatible with older versions of Windows.

@DGA
I think I made a mistake and the value should be set to 0 rather than 1

EDIT:
Actually not, it's should be 1

DGA · Dec 7, 2023

Ha Ha I actually tried both because its worded in the negative

DGA · Dec 7, 2023

Hi Guys. I am going to give it a break now and have had the benefit of you time most generously. Thank you. It must be hard coded in.
Cheers

zebal · Dec 7, 2023

You can always move the file to different location that is shorter or rename it to shorter name.

Why not running BlueRobot's reg commands to confirm you did it right?

DGA · Dec 7, 2023

Thats the work around I have been using but decided to day to do it properly. So back to work around for now. I don't know what running those Reg commands means and looked for txt file but could not find it.(Searched for all txt files as well) I know nothing about this stuff so I will go and learn and come back another day.Thanks again

DGA · Dec 7, 2023

Thanks Zebal. I have a long sequence of logical folders in the path and the file name is actually quite short.Thanks for advice
