Is there a quicker way to set background images?

Easier to fix your config than re-create it, if you still have the config there and the folder formats are just pointing to the wrong drive letter.

  • Fully exit Opus (via File / Exit Directory Opus).
  • Open C:\Users\<username>\AppData\Roaming\GPSoftware\Directory Opus\Formats\folders.off in your favorite text editor.
  • Save a backup somewhere.
  • Do a search & replace of A:\ to B:\ (or whatever the letters are).
