Yes, it is possible with certain limitations:
- Both parent folder and child folder (subfolder) must have Read & Write or Owner permissions.
- Both folders are treated as separate sync folders, so additional indexing will be done.
- Other peers that have the same parent folder will NOT seed the data to peers which have only the child folder (see the figure below).
- Both parent folder as well as child folder must have "Selective Sync" disabled.
This figure illustrates syncing child folders (subfolders) as separate shares. On Peer1 computer there is a folder A, and B is its subfolder. Both A and B are added to Sync as separate shares: A is shared with Peer2 and B is shared with Peer3.
In this setup, Peer1 and Peer3 will be syncing only the content of folder B. But Peer1 and Peer2 will be syncing both: A - as a sync share, and B - as a subfolder of A.
The side effects of such setup are:
a) heavy load on Peer1. Folder B will be indexed and rescanned twice - as a subfolder of A-share, and as a separate share.
b) if Peer3 makes changes to files in B, they will be delivered to Peer2 all the same: from Peer3 synced to Peer1 within B-share. Since this directory is also a subfolder of A-share, files will be synced to Peer2 within A-share.
