Hello, How does "sync" work exactly? Is there a master/slave relationship between the machines? I tried with 3 PC (W7/XP/SBS2011): I've installed 1st on XP then on SBS (Windows server) and then on XP. SBS and XP got synchronized (from W7) immediately. Then I removed a directory on XP. The directory files (I read that BTis working on removing the directory itself) got removed (almost immediatly) on SBS, but not on the W7 machine. Then, after some time (approx. 5min) the files were reinstated on both XP and SBS (like if W7 was the "master"). Can someone please explain me how it is supposed to work? Thank you very much.
