I move my files to a different folder now LR doesn't know were the original files are located. I get the following message when I try and delete a file "The original file can not be deleted because it is missing or on a volume that is offline." How would I reestablish the connection to the new file locations?
You should also see an "!" mark on the top right corner of the thumbnails.
Click on one and choose Locate. navigate to the location of the file and click select.
If you also check the box "Find nearby missing photos" lightroom will reconnect all others in the same folder.
Repeat the process if you moved the images to different folders.
