Moving Catalog and removing uneeded backups
I have been keeping my catalog on my dropbox and it is clearly not a good idea. I would like to move the catalog to its default position and remove any unneeded backups and other debris in my backup catalog folder, which to me looks like a mess:

If someone can point me the the best way to move the catalog file ( I have looked at a few tutorials and to be honest it seems overly complicated to move, then add a single image, then...) and also what to do with all these files? Also, I would love a strategy for keeping an additional backup that is not on my desktop?
