Hmm. Yes, that is an interesting use case. Keep in mind that this would require some additional plausible deniability (PD) logic fenangaling on the part of the user:
- The difference between the Data folder PD and the PD you're describing is that Espionage takes care of creating fake data for *everyone* for the Data folder.
- Therefore, it would be known that unlike every other Espionage user, you chose to manually run the assistant to generate fake data on the external drive.
- Therefore, it would be likely (depending on how you set things up) that on that drive you have one "real" disk image, one or more decoys that you manually created to show off, and one or more fake disk images that Espionage created.
That is still
*much* better than having just one disk image on that drive. Also, you don't have to do it that way. You could, for example, create fake disk images on *all* of your external drives, increasing your PD even more.
To be honest, implementing this feature request is fairly low on our priority list, as I'm guessing it's not something most users will find themselves wanting to do.
For now, however, what you can do is quit Espionage and rename the
com.taoeffect.Espionage3 folder to something else (
*don't delete it or you will lose your data!*). The next time you start Espionage it will re-run the PD assistant and will create a new "fresh" (but randomly timestamped) batch of fake disk images for you in the
Data folder. You can move these to your external drive as you desire. After you're done, quit Espionage and restore the original
com.taoeffect.Espionage3 folder, making sure to place it where it was in
~/Library/Application Support.
Finally, make sure to create at least one decoy Folder Set and encrypt some semi-incriminating folders on your external drive (make of that what you will

). If the folders that you drag into Espionage are located on that external drive, it will ask you to choose where to save the disk image, so you can place it next to the fake disk images.
Hope that's helpful! Let us know if you have any other questions!
