In the Application Options section you can change the default location that Booth stores all of your images, events, screens and print templates. All of these items are managed by Booth and must me stored as a group. It is best to leave everything at the default location but if you need to relocate your data contact support for information on the proper procedure. If you change this without relocating all of your events, screens and print templates Booth will no longer be able to locate them. Changing it back to the default will fix the problem. The default location in Windows 7 and 8 is C:\Users\Public\Documents\Darkroom Booth\Photos
