Trouble is, I don't keep user data on drive C if I can possibly help it. I want to be able to wipe drive C if ever I rebuild Windows, and Microsoft make it pretty difficult to have one's \Users folder anywhere other than drive C.
I kind-of agree with you, not so much about wanting to rebuild Windows but because the AppData folders are buried in a system area that is easily forgotten when backing up. I'd rather keep such user data with other work folders.
What I do is put these folders on Dropbox, using a symbolic link
. This means the presets, templates etc are automatically synchronised on multiple machines.
It ought not to be a recipe for confusion: the catalogue is, after all, where one would logically keep user data.
Ought not, but usually is. For instance with Gary's current setup of two catalogues there will two sets of preset folders in addition to the AppData default one. Each catalogue has its own set of presets, so when you save a Develop preset in one catalogue it won't be available in the other, and updating a preset causes a similar problem.
