Is it possible you accidentally opened a new catalog and imported photos into that new catalog?
If you go into Lightroom and try File->Open Recent and open the catalogs listed there, do you find what you want?
If not, then we need a lot more detail about what you did ... exactly what functions/commands you used (use the exact name of the function or command, in other words, there is no "get" function; and what software these were a part of, Lightroom or Elements or operating system), and what happened. Also please state the exact version of Lightroom and your operating system.
Hi dj, Thanks for your prompt reply I still cant find my folders,I will try and explain what I did.I was working in Lightroom 5.6 and there were some files in PSE 12 that I needed to work on in LR and I didn't seem able to transfer them over,so in LR I clicked on File>upgrade PSE catalogue a box appeared asking "Would you like to upgrade PSE catalogue to use with LR" destination [ C:\users\Robantlyn\pictures\lightroon\lightroom 5 catalogue 2-lrcat] I clicked Upgrade and waited until things were sorted.When I checked the folders and collections panel non of my LR folders were there! only the ones I had just upgraded from PSE and I cannot find them.When I did what you said all that came up were the ones I had just imported.The total number of photos shown at the top of the folders panel shows 1663 when before I had over 7000.I know probably at fault here as I am not an expert so I hope I have'nt lost everything. Thank you in advance
File->Open Recent should work, one of the catalogs listed there should contain your previous work
Hi dj Yes it worked !! a very BIG THANK YOU
