Lightroom Classic: Closes when resulting file name after move is too long.

Bug report.

I have many files with really long filenames (> 200 characters). When I move them (drag and drop in the left pane), if the resulting complete file name (folder + file name) is too long, Lightroom closes without any error message. If I try again, it closes again. If I change the filename for something much smaller and then move the file, it works.

Lightroom should show an error message saying that the resulting complete file name is too long instead of crashing silently.

I have tested this many, many times in the last two years.

Thank you.

I think the LongPathTool software can help. It should work with the issue.
Saved my project. Try it!

You are running a pretty old version of Lightroom Classic (7.3) - The current version is 8.3. Is there any reason you are not updating?

Rikk, no reason at all. I bought the cloud version of Lightroom and I always say yes when any app get a new version. From what you're saying, I conclude that my version of Lightroom doesn't check if a newer version is available. I have to check why. Thanks for the hint.

That being said, does the latest version handle correctly long file names ?

Rikk, thanks for all you replies, I really appreciate ! I just understand why I was not up-to-date : I have disabled the automatic launching of the Creative Cloud app last year. That was a mistake I think. I just launch it and it asked me right away if I want to update Lightroom and Photoshop. My problem may have been fixed, I will test it in the next two days.

Carlos - This is what I do. But no software should crash without error message because a filename is suddenly too long. That's basic error checking.

Just tried with the latest version : still crash Lightroom if the resulting filename (folder + filename) is too long for Windows. Shame on developers.
