some possible improvements to the Photo Library module :
Delete an image from the catalog without erasing it from the hard disk
Modify the acces path for a batch of files (when they have been moved with the Finder, for example)
Find virtual copies
Remove the contents of an external drive from the database after working on it
As @Joanna mentioned there is no catalog like Lightroom. All that is in the database for any image file are the edits to that file and added keywords. You can not delete an image so it is no longer visible in PhotoLab without deleting the actual file from your hard drive.
You can accomplish what you want to do in Lightroom because you must import file locations into its database catalog before being able to edit images. As a result you can delete catalog entries which will result in images no longer being available for editing in Lightroom. Photolab does not include an import feature and does not have the functionality you are looking for. I hope that is clearer for you.
@leraymur, if I understand you correctly, you propose a functionality that allows selective removal of data from the database. I also feel that this proposal is just one possibility of what you actually want to achieve.
In other words, what good is it to develop a cure if we don’t know what sickness it should treat?
I’d try the following (one at a time to see if it changes anything)
point DPL to a folder that does not contain any images or folders before you quit DPL.
delete the cache files (quit DPL before you do this)
As long as you work on the same folder and have not changed anything using the finder, you can work as usual. Before modifying anything in the folder structure, I’d quit DPL.
Thanks for your answer, but it doesn’t work …
Too bad, I will delete the thumbnails with “?” When I meet them (I think there are a few thousand …)
It is annoying, but not serious.
Thank you
