If you’re like me, you set up custom Workspaces in Adobe Photoshop. I like having certain panels located in certain places, some fully open, and some reduced to icon-only state. Saving those panel locations makes it easy to return Photoshop to your preferred setup quickly and easily if you move Panels around during a work session. It also allows you to have different configurations for different tasks, such as one setup for general Photoshop work, and another for color correction.

Recently I did a clean install on my MacPro, and wanted to pull my custom Workspaces from a backup so I wouldn’t have to re-configure them – a time-consuming task. But where does Adobe Photoshop store these custom Workspaces?

They’re found where you would probably most expect them to be:
Users/[your user name]/Library/Preferences/Adobe Photoshop CS5Settings/WorkSpaces

Make a backup copy of this file for easy recovery if you decide to reformat you drive at a later date – it’ll be easier to get up and running again when the time comes.

And if you’re interested in finding where other custom files and preferences are stored, you can visit this knowledge base article on Adobe’s website.
