I was looking through all my photo files and when I went back to lightroom everything was gone except one little group of photos. 2600 images. Where are they??
Which version of lightroom?
Mac or Windows? Which version?
Are the image still on the hard drive(s)?
Are the images still in the catalog?
Was Lightroom still running when the files went missing?
Do you have a recent backup of the catalog?
It is possible you accidentally opened the wrong catalog file. Use File->Open Recent and select each item in that list to see if the catalog you want opens.
Thank you, I did just that and it worked. I'm not sure what happened but it's fixed.
