Windows 11 Pro Version 25H2 (OS Build 26200.9168)
Hi. I am running Windows 11 Pro 64-bit, Version 22H2 (OS Build 22616.100)

I first tried Apps & Software, here ( ), but now feel the issue is within the Win 11 beta build. A post suggested checking the registry (Maximum Path Length Limitation) to turn on extending the max file length. I found everything in the registry was all set for long file names so why I get this error is confusing. I don't have a clue what's wrong.

BTW - the software giving the error is an older program but has always worked fine over the many Windows OS changes.

Below is the error & the text.

All suggestions are appreciated.

I doubt there is any solution. Long filenames have never worked properly.

Far simpler to just ditch an old backup tool and use a nice shiny new one

You do not say what is being backed up i.e
is it just data, or image backups.

You responded to my other post. Thanks again.

This problem was not present in Win 11 until I tried the Win 11 beta version. And, yes, it's an older program I use for backup - Oops.

AOMEI looks to a good backup. But I don't want to give up & pay $100 for 2 PCs just yet. I'm using a trial version of AOMEI now but see no advantage over Oops; that is, if Oops will ever work properly again. o_O

The odd thing is Oops will backup anytime I open my backup drive. And I can browse the files directly on the HDD & retrieve what I need. What I can't do is open the Oops app & use the app software to retrieve data. When I try to open the app is when I get the long file name error. I'm guessing that long file name is the Oops product key which was extremely long.

The free version is fine. You have downloaded wrong version. Of course the free version is less feature rich than the paid (trial) version but still good enough for most users.

Hi there

while most apps are still using essentially the "Windows explorer" API which still limits long path / file names to 266 chars some modern apps such as FileZilla use the new internal API which DOES allow long file / path names -- you need to enable the feature somewhere in the registry though --forgotten where at the moment but it's "do-able".

Cheers

Thanks, jimbo. But as I mentioned, every registry location such as in the image, were already set for longer file names & the app still errors.

Hi there

@GARoss
It doesn't matter if that bit is set if the API used is still calling the "base File explorer" API.

For example filezilla shows perfectly Very long file names from my NAS server == Filezilla running on Windows.
It's whether the app uses the old or new API. !!!!!

I'm guessing old APL as I purchased the app more than 10 years ago.
