Files names and Tree Structures of more than 256 characters

[Shak1990]

What's the Problem?

Please add support for long nested paths and file names of more than 256 characters.

Solution/Idea

Add support for file names more than 256 characters and tree structures longer than 256 characters I think by changing/adding a registry key.

Files already supports this. The limitation is with windows and will have to be disabled from it. there are guides on google for this.

Are you sure? because I changed my registry key and followed this guide:
https://helpdeskgeek.com/how-to/how-to-fix-filename-is-too-long-issue-in-windows/

But I am still not able to create a folder with a name length of 260 characters.
Another example is if I create folders inside folders with a total length of 270 for example and when I try to move it from Drive D to F I get the error File name is too long.

I am on Windows 11 latest version and I am using File's latest version from the store.

Moreover, please try for yourself and create a folder with the name "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzlmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz" and add another folder with the same name.

You will see that even though you changed the registry key to supporting long file names/paths you are still not able to do so.

Please reopen this feature because it does not work as you said!

The problem is Windows supports a Long file path but File explorer does not therefore you can not move or create long path files/folders structures.

I have tried it. and if file explorer is still giving you the error then you havent done correctly. Did you restart after making the change.

[Shak1990]

Could you let me know what you did differently from me?
I changed this registry key to 1

And yes I restarted my computer several times

Did you read the links I send?
This is not my problem if you search on the internet you will find out many people have this problem.

To be clear you are able to do this?
"Moreover, please try for yourself and create a folder with the name "abcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzlmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyzabcdefghijklmnopqrstuvwxyz" and add another folder with the same name."

Right now I can't do the above, I am trying to create a new folder with a name longer than 256 characters nothing happen, and if I am trying to create a folder with let's say 10 characters that will have more than 265 characters in a total of the tree structure I will get an error like in the feature request image.
The same with copy and paste folder from let's say "D" drive to a nested structure inside "C" I would get an error too that the path name is too long.

[Josh65-2201]

I have done this and the same way it does work for me. In any case this is a windows issue and not a Files one since it doesnt work for File explorer. Files wont be able to do anything about it.

I managed to create deep folder by sharing the deepest folder, and add new folder remotely. But it only works for another 255 char (you need to share again for next 255 char again.. and again.. , or just use 7-zip file manager as your windows explorer.) This "unlock" will not automatically applied to other folder.
Additionally, even though Window Explorer can then read the deeper folder, it cannot open the file (if any, I cannot create new file text using windows explorer but create with 7-zip instead) with Windows Security - These files can't be opened "Your Internet security settings prevented one or more files from being opened."
I'm imagining if we can do like compressed file do: move them first to temporary folder (that makes filename limitation though..) and then open it from there.

Why did this close? @Josh65-2201 I tried what @Shak1990 said and he is right you can not create a folder with a name of 250 characters in length inside another folder of the same length.

[Josh65-2201]

This is a Windows limitation it would be the same for other explorers. For whatever reason they remove or changed the way of unlocking it.

I have to agree with itayasaf1991xd. I tested with Windows 11 on Drive C: (fixed NTFS volume) with LongPathsEnabled=1 (rebooted) and I was limited to a maximum path length of 260 characters using either File Explorer or Files.

Using Directory Opus, I created a folder structure with a total path length that was thousands of characters long (10 levels deep). I created each nested folder with a name that was 256 characters long (the max for an individual folder).

File Explorer had no problem navigating the deep structure (whether LongPathsEnabled was set to 1 or 0). Files displayed an 8.3 name for the first nested folder, and then opened File Explorer upon double-clicking the second nested folder.

Both Files and File Explorer were unable to create a folder structure with a total path length that exceeded 260 characters. File Explorer would politely display an error message. Files just ignored the attempt.

This is a Windows limitation it would be the same for other explorers. For whatever reason they remove or changed the way of unlocking it.

Maybe take a look at how Directory Opus does it:

Leo, Directory Opus developer, Nov 23 20:

"Behind the scenes, Opus adds the \\?\ prefix automatically for very long paths."

I think you're misinformed.

According to Windows' documentation , once the path limitation is disabled windows is able to handle paths of approximately 32,767 characters in length.

I confirmed that works with apps like Windows 10 video player and PDF X-Change editor if you open the files from within the application's file picker. Powershell also can, via specific commands, manage and access those files because it has builtin facilities to call the Windows API directly.

NTFS's latest version also supports long path names, so it's indeed File that is at fault here, since it's perfectly possible to implement it correctly, like the apps I mentioned above do. It's just a question of willing to put the effort into it.

So no, this is not a Windows fault.
