I did not found any solution. Any Ideas? Is it possible to get an export from my linked files (cvs,txt,sqlite3) - so that I can clean up my files with my own scripts?
- there are two things I do not understand
1) why It's not possible to check new imports against the whole source images? If I deleted images they will be reimported
2) why there are no export from the database like metafiles,linked source,.... available?
Reimport the photos that are NOT in Lightroom by checking "Don't import Suspected Duplicates" and creating minimal previews in the Import dialog.
Select "Previous Import" under the Catalog section of Library.
Select all these photos.
Right-click one photo and select "Remove Photos"
Click "Delete from Disk"
Thank you! But is there no way to do it for all files? In my case I have 500GB data and there are not more then 20% in LR. My Macbook run out of space! :(
