I use sophisticated folder structure for wildlife photos, with sub-sub-sub-subfolders for animal classes, families and species. So I have folders like ~/igor/Photos/Animals/Birds/Sheathbills/Snowy_Sheathbills/2020.08.17_Place_name.
Some less sophisticated structure for other photos. Eg. ~/igor/Photos/2020/Portrait/2020.07.11_Session_name. with subfolders like …/Processed_BW or …/Processed_Bright etc for different purproses.
So I prefer to sort photos in external software - copy from camera’s card by filemanager and view/sort in Rawtherapee as RT’s view/sort tools (especially “inspect” module) are more convenient for me. I “only” use DT as RAW processor.
I have set Settings > Import > Import > “Recursive directory traversal when importing” to OFF , to not show all processed JPGs alongside RAWs in Lighttable and Darkroom.
After sorting, I choose folder in my external software (or in filemanager) and choose “Open folder with > DT”. So I just get DT opened with freshly imported filmroll containing only RAWs from main folder, without processed JPGs from subfolders.
Until this moment, Easy and clear. BUT. I get big mess in “Collect Images” module. I cannot just click on “filmroll” and delete from database.
Is there any method to purge collections automatically on exit?
