Bug description

From PC (windows) /Smartphone (Android) chrome browser, only on the directory /Camera of user admin, I can see the image/video in the folder (the thumbs) but when I click on it to expand I have a black windows and the error below.

Image/video in other folder of the same user are ok.
Image/video in other folder of other user are ok.
Priviledge and ownership of the image/video seems the same of both image viewed and not viewed:
-rwxrwxr-x 1 www-data www-data

The same image/video on Android app is open without any problem.

I try by deleting nextcloud, reinstalling it, re-put the image folder in it, re-create the previwe, but the problem persist.
I try by deleting the chrome cache, by opening an incognito windows, but the problem persist.

The folder is the main folder with a big number of photo and video, but I have another user with another big folder that don't have this problem. So I'm not recognizing any pattern for now.

Steps to reproduce

I wasn't able to reproduce a pattern: Just clicking on an image/video on a specific folder in the brower and it open a black windows instead of the image/video itself.

Expected behavior

When you click on the image you should view the "bigger version", if you click on a video, it should start the video reproduction.

Please provide an example folder structure and sorting order with which this can be reproduced. This probably depends on what else is present in the folder, not just the file to be opened.

[thlehmann-ionos]

Note: in fileUtils.ts in genFileInfo() it's problematic to test any field to be numeric (castable to Number) and then converting it to number. Whether or not this is the case here (steps to reproduce inadequate), I can see, that this leads to problems if the basename attribute happens to be a file or folder name which resembles a number (i.e. "123"). When casted to type Number later comparisons in sort functions will fail due to Number not implementing localCompare(). Whatever the steps to reproduce are here, genFileInfo() should be more specific/careful when converting types from the server responses.

Side note: this is an error in the Viewer app (which has its own issue tracker).

Hi,
The folder Camera was directly in the root of my admin account, so I had something like:
/data/admin/files/Camera

the file in it was photo and video uploaded from an android smartphone, so this is some filename example (are underd of file, so is difficult to report everyone):

trying to disinstall and reinstall it didn't solve the problem.

Instead I solved he problem (for now) by cancelling the folder, creating a new one with the name "Foto" and then re-upload everything from the smartphone.

Maybe there was one file that create this problem that I didn't re-create by uploading everything from zero?

If the problem re-apper I'll check better filename.
