[Digikam-users] workflow for deleting not wanted RAW-Files

I would have used Ztree to delete them, not sure if there's an equivalent file manager in Linux.

I would tag all the jpg files in the affected folder, then use the control+Batch command to use the base of their filenames to create a batch file to rename their matching raw files to, say, *.rawsave. Then I'd delete all remaining raw files and rename the rawsave files back to raw. I assume digiKam can then work out which thumbnails to get rid of.

This procedure could also work for multiple directories. You could do it the same way by manipulating directory listings into scripts by hand if you find Ruediger's scripts daunting.

It sounds like digiKam needs a way for raw/jpg pairs to be able to be treated as one unit, like Lightroom's stacks. Doing it with scripts is bound to lead to tears sooner or later.

Hello Ruediger!

Wow, thaks a lot for sharing these scripts. Looks like they do what I want... have not 
tested them yet due to lack of time.
Anyway it seems like there is no "internal" fuction in DK, since nobody else replied.

Thanks a lot again
