Description sunphoenix@hotmail.com 2022-06-08 18:19:40 UTC 
SUMMARY
When I rename a folder and just change the case, DigiKam detects it as a different new folder/album.

STEPS TO REPRODUCE
1. Make sure folder xyz is in present as an album.
2. In file explorer, rename folder by changing letter case only.
3. DigiKam automatically detect as a new folder and will also find them as duplicates if you search.

OBSERVED RESULT
There are multiple albums that point to same real location on disk.

EXPECTED RESULT
Only one folder/album. No duplicate detected.

SOFTWARE/OS VERSIONS
Windows: 10

Are you using MySQL/MariaDB? This has already been fixed in current digiKam versions. But, we don't do an automatic database update. You need to migrate your database to a new database using the digiKam Migration Tool.

Yes I can reproduce it, it's another cause. if the change is not at the beginning, Windows manages different upper/lower cases.
