Description gudvinr+kde 2024-04-09 15:36:48 UTC

SUMMARY

If you open .iso file in Ark, it shows all names in upper case.

But KIO module that mounts same iso shows filenames correctly.
As well as "iso-test --udf %filename%.iso".

Important note:
When extracted, files also extracted with upper case names. That breaks software on .iso that expects specific names.

STEPS TO REPRODUCE
1.  Open .iso in ark

OBSERVED RESULT
Names incorrectly shown in upper case.

EXPECTED RESULT
Correct letter case.

Do you have a test ISO file that you can attach here?

Comment 2 gudvinr+kde 2024-06-10 06:14:35 UTC

Unfortunately, no. I noticed that while I was working with private software distribution. Not only it's private, it's also pretty big ISO.

But I can show you info dumps.

From what I see, KIO recognizes ISO as UDF but Ark doesn't. But it does have UDF metadata

Comment 4 gudvinr+kde 2024-06-10 06:20:00 UTC

Also output from blkid -p:
