Hi, seemingly editing enough photos from an external USB drive in Gwenview will eventually cause the drive to have missing files, and no longer show all of the drive's files unless you run a filesystem check.

STEPS TO REPRODUCE
1. Put a large number (68 or so in my case) of TIFF scans on an NTFS-formatted USB stick. You can download https://archive.org/details/Ford-Times-May-1978 and extract the CBZ file to a drive to recreate my setup.
2. Open up the first file in Gwenview, and crop as desired.
3. Keep cropping successive files until Gwenview shows you the first file

OBSERVED RESULT
Gwenview unexpectedly wraps around to the first file before you've gone through all the files on the disk, and checking the disk shows files missing from the drive.

EXPECTED RESULT
You can safely crop all of the files, and everything is still present on the drive at the end.

Got it to happen on my Neon Unstable testing laptop:
Gwenview 24.04.70
Operating System: KDE neon Unstable Edition
KDE Plasma Version: 6.0.80
KDE Frameworks Version: 6.0.0
Qt Version: 6.6.2
Kernel Version: 6.5.0-18-generic (64-bit)

Product Name: Inspiron 3520

Edited 30 photos (same kind as my test images) with cropping quickly, saving each one before moving on to the next

I also have the error reports from checking the disk on a Windows laptop, and then repairing after errors were found.

Thank you for the bug report. Unfortunately we were not able to get to it yet. Can we ask you to please check if this is still an issue with Gwenview 25.08.0?

Comment 3 Steve Zakulec 2025-09-02 13:56:48 UTC

Recently got back from vacation- haven't tried this yet.

Comment 4 Steve Zakulec 2025-09-06 22:13:17 UTC

Just tried this again, on a Sandisk external USB-C SSD drive, and I couldn't reproduce it.

Updated details for system below:
Operating System: KDE neon User Edition
KDE Plasma Version: 6.4.4
KDE Frameworks Version: 6.17.0
Qt Version: 6.9.1
Kernel Version: 6.14.0-29-generic (64-bit)
Memory: 16 GiB of RAM (15.5 GiB usable)

I'll try to dig out the original drive I tested this on.

I can't reproduce this now, including on the original drive, so the bug can be closed now.
