I have copied all my files to new 4TB WD Elements hard drive as my 2 TB hard drive was running out of space. How do I map my library to the new photos without losing all my edits and collections? When i remove my old harddrive, all the catalog files locations are lost and I don't know an easy way to map it to the new location without going into every folder and mapping each collection.
What is the name of the application and the version of the application you are using?
In your scratch disk setup you can specify the location.
