Three way sync with FreeFileSync?

[eXor]

I'm trying to figure out the most efficient way to set up FreeFileSync for the following scenario :

1. Do some work on PC-1 at Location A
2. Perform a 'Two way' sync between PC-1 and FlashDrive-1
3. Transport FlashDrive-1 to Location B
4. Perform a 'Two way' sync between FlashDrive-1 and PC-2
5. Do some work on PC-2 at Location B
6. Perform a 'Two way' sync between PC-2 and FlashDrive-1
7. Repeat from step 1

Possible with just one folder pair?

Yes, that's exactly the kind of scenario FreeFileSync was designed for, except you left out a couple of steps:

7. Transport FlashDrive-1 to Location A
8. Perform a 'Two way' sync between FlashDrive-1 and PC-1
9. Repeat from step 1

It's stating the obvious I suppose, but I thought I'd better point it out for the sake of completeness - in other words, you just need to remember to do a two-way sync to the flash drive *both* before and after you work on *either* PC.

edit: I'm guessing Dropbox (or one of the many alternatives) isn't an option for some reason?
