Tips for using MSN Messenger to quickly transfer files between Intranet users

Instead of sending files as soon as they come up, simply say a word and then upload them.
If a file is uploaded as soon as it comes up, it may take a long round to go to the public network, which is very slow;
If you say a word later, it is estimated that messenger has learned the shortest path, which is directly transmitted in the Intranet. Of course, the speed is fast.

I found out this tip a long time ago and thought everyone else should know it. Today, I saw my colleagues passing documents at the same speed, and I casually reminded them that they were all surprised that the speed was quite different, so I wrote this tip.
