Ercan Cem asks:
How does Google Chrome Sync work exactly?
Say I have bookmarks at computer A. I sync them; now they are stored in the cloud. I go to computer B, with a freshly installed Chrome. I sign in, and get the bookmarks from the cloud. Now here comes the tricky bit: I again sync bookmarks from computer A. Now, say, cloud has bookmarks “A2″. Then go to computer B and play the with bookmarks, and, at that moment I have “B2″ (previous state was A1.)
Now when I sync, how does Chrome knows whether I want cloud to be synced to A1 state, or want PC B to be synced to “A2″ state? Was that confusing?

March 17, 2012That’s a good question.
Basically, how it works is that Google Chrome sets up a connection to Google’s servers with XMPP. XMPP is the same protocol used for Google Talk chats.
When you delete a bookmark on computer A, computer A sends a small message (kind of like a chat message) to Google saying “hey, this bookmark was deleted.” Google then sends a chat message to computer B saying “hey, delete this bookmark.”
So it doesn’t just sync all your bookmarks as a big blob, it’s smart enough to only sync individual bookmarks.
This is explained at the bottom of this page: http://www.chromium.org/developers/design-documents/sync

all files are uniformly copied to all 3 places because you are using only one account i guess..
