Dropbox- Enable LAN Sync

Imagine a situation where you have Dropbox installed on your desktop and you drop some files into the Dropbox folder.
What happens next?
  1. Files are uploaded into the cloud (Dropbox servers)
  2. Dropbox server gets the file(s) and look for an existing match on its servers.
  3. If file is new (or modified) it sends sync request to the entire linked Dropbox clients
  4. The new (or modified) file(s) is downloaded to the linked clients
  5. Sync is complete
That's fine and works great.
But what if we can change the speed of sync process to be much faster?
Well, Enable LAN Sync can reduce the time of sync process- It actually does only steps 1,4 and 5, leaving the slower steps 2 and 3 behind.

How does it happened?
  • You must be inside a LAN environment with your other linked client.
  • You should enable this feature in your Dropbox client:
Right click mouse on your Dropbox icon and click on preferences
Check Enable LAN Sync

So you will ask a question- Why not to check this feature by default forever?
Well, it needs your firewall to allow a port for the Sync to be opened leave this port vulnerable.
Also it makes some network noise on your LAN.

Following the last paragraph- Another scenarios to use it?
mmm it can sync your mobile faster in case your desktop and mobile are on the same LAN (Wireless/Wired router) and it can sync your desktop and Media Center with large GB movies.
