Yes, you would move the catalog file by using your operating system, and then when its on the other drive, double-click on it.
You probably want to move your photos too, again do so using your operating system and keep the folder structure unchanged, then reconnect in Lightroom by following the instructions in this article (see Figure 4): http://www.computer-darkroom.com/lr2_find_folder/find-folder-old.htm
Thank you dj_paige
Sounds good. I will give it a go.
And thank you again
Yes moving the catalog and then clicking on it worked fine.
as my photos were on a remote drive i didn't need to do anything. Lightroom still knew where they where.
The link you sent was a waist of time for me. He explained how to do it in Lr and then at the bottom said there is a better way. And there is a better way as he then explained. Simple.
Thank you again for your quick response.
I was able to fix it fast.
