Thanks for the reply RomanZ
my case is this: PC1 (RW key) VPS1 (encrypt key), all synchronized, so everything is right something goes wrong and dies PC1 and VPS1 but from this I pull out the encrypted folder intact. I move the encrypted folder on VPS2 and connect the folder with encrypt key (the same as VPS1) and obvious message "Destination folder is not empty. Add anyway?" Finally setup PC2, with RW key the same as PC1 in the tests I've done, VPS2 does not transmit data to PC2, however, if PC2 adds a file works Encrypted files in VPS2 are not erased and not even modified there are limitations in this regard? the encrypted folder must have the same name and the same position in different VPS? it is necessary to wait and/or force rechecking? ps. I used the same version for all peers
