I wanted to share a folder from computer A to computer B via BT Sync. Here is what I did. 1. I added the folder to BT Sync on computer A. 2. Since the folder is really large, I pre-copied all the files to computer B. 3. Before I connected the two folders on the two computers, I did some change on computer A. The changed files had newer modification time, so I supposed that they would be copied to computer B once they are sync'd. 4. I created a link in BT Sync on computer A and opened it on computer B. When prompted to enter a destination folder on computer B, I selected the pre-copied folder. After the two clients finished sync'ing, I found that the changed files on computer A were reverted back to the old version. I wonder if this is a bug or intentional for some reason.
