Hi, I have to check with developers. I see a small possibility of:
- giving an (emtpy) folder to Espionage to encrypt
- creating by hand a disk image with same characteristics (name, size, encryption) as Espionage did, except selecting different filesystem type)
- disable the folder in Espionage
- delete the Espionage created folder and replace it with the one you created
- enable the folder in Espionage
I guess Espionage would not realize the hack and would accept the disk image as its own (child

)
I will see with developers if they have anything to add and let you know.
Cheers
Zsolt
