What are the MUST BACKUP files for Photoshop?

[grwiffen]

I am having to completely rebuild my PC as the motherboard has died. I managed to save the hard disk, but it having to be re-formatted.

I will be able to access the system files before hand.

Can anyone please tell me which are the MOST IMPORTANT files to get access to for Adobe Photoshop, Bridge and Lightroom?

Bridge: I think Bridge keeps the Keywords in a seperate file, which Id love to get hold of, to stop recreating this list.

Lightroom: keeps a Catalog - does anyone know which files this is and where it is located?

Photoshop: Im not sure what files I need to copy.

All guidance gratefully recevied.

Thank you in advance.

You'll find the preference files in <user>/App Data. Photoshop's are in <user>/App Data/Roaming/Adobe.

In Windows the Lightroom catalog is I believe by default in you Pictures folder, inside a Lightroom folder, unless you designated it to be saved elsewhere. You can check where it's saved in Edit>Catalog Settings.
