Description crowfunder 2025-08-05 17:08:38 UTC

SUMMARY
It would be amazing to add an option to change the directory in which AI model files will reside. My main drive with LocalFiles is pretty small and I'd like to download the model files onto another drive.

STEPS TO REPRODUCE
1. Attempt to download AI model files.
2. Download path is permanently set to Appdata/Local/digikam

OBSERVED RESULT
Unable to change the model files download path

EXPECTED RESULT
Ability to change the path where the model files will reside.

SOFTWARE/OS VERSIONS
Windows: 11 23H2

add option to configure Face Engine model data path in the digikam_systemrc
It is also possible to have a data package in the system or
user directory under Linux or Windows.
For Showfoto, the digikam_systemrc is also used for the model
data path to avoid duplicate downloads.
Configuration in the GUI follows...

We should consider whether, if files are present in the old location, we should copy them to the new one.

Perhaps an option in the settings to migrate the model files into another directory.
