I would like to add a whole disk (FAT32) to Picasa folder management. It's a data disk my girlfriend (using Windows) and I share. But I can only add folders from the disk Picasa (and Ubuntu) is installed on. How can I add a whole disk to folder management?
I haven't ever used Picasa, but I would suggest that you add the disk to your filesystem in Ubuntu.
Then it is the same as using a local folder, and is also available to any other programs that you wish to use.
