Stop whatever you're doing, or you may overwrite the data that is likely still there! Now go to the Trash (Mac) or Recycle Bin (Windows) and move the catalogue file out of the Trash (Mac) or restore it (Windows).
Thanks - yes I tried that but it still would not read the file
I have back ups of all the image files and know they safe but the catalog in Lightproof is empty. is there anyway to recreate a catalog linking to existing folders in explorer?
Were you doing the weekly catalog backups (or whatever schedule you preferred)?
If yes, then copy the most recent backup into the original folder, unzip it as necessary.
Yes I was - Thanks I will give that I try although I think it was backing up to the same folder that got deleted.
