I am a travel photographer and I use my Laptop for editing on the go (Mac) but my main workstation in my office is a desktop (PC).
Is there a way to sync my presets across devices? It's such a pain to have to manually update the presets every time I edit.
The easiest way I can think of would be to set the default location for presets into a Dropbox folder, but I can't find a way to change the default presets location.
I would suggest using a temporary travel set-up “On location catalog” and then merging into your master catalog.
Here is a useful video tutorial at Adobe TV.
There is no syncing of presets. Those files require manually copying and also manual backups.
