I am having trouble, i recently switched over to an external Hd and my files were coming up as file missing. ive since figured out the fix for that but i deleted a few folders and now if i try to reimport i cannot/there isnt even a folder showing the missing files or thumbnails. so my question is how do delete them from my harddrive so i can reimport the photo's? ive went into my c:drive but i am not sure where to go from there? the photos in question are all from the same date so i only want to delete those if possible........Help!
If they were already imported you should re-link them instead of re-importing. Find the folder in LR and follow these instructions: Lightroom thinks my photos are missing—how do I fix it? | The Lightroom Queen
With re-importing you will loose all the work done on these images.
Just in case: To be able to re-import you'll need to remove the images from LR - do not import duplicates by disabling the option that stops you from doing that.
Thanks. they were already imported but i transfered them to ext harddrive and werent showing up but whwn i put the sd card back in they appeared and were editable .
