I have LR5 running on a Mac under Yosemite OS X 10.10.4. I would like to delete a number of old images from my LR database but when I try I get the response (e.g.) The file named “DSCF1860.JPG” could not be moved to the Trash folder. This happens on ALL images more than about 7 years old. Has anyone else experienced this? Can anyway help? Thanks!
The images that you are trying to delete from Lightroom, are you trying to delete the images within Lightroom or out of Lightroom.
I would suggest to remove the images from the Library Module of Lightroom, and when you delete the images, you will get a prompt to " Delete from Disk '
So selecting that option, will remove the files from the computer.
Please let us know if it helps.
