I am just curious about this.

I had a network folder open on one computer viewing the files in the folder. From another computer I opened the same folder on the network and deleted a file. On the first computer the deleted file immediate disappeared from the list.

The only way that I can think of how it knows that is that it is constantly checking the contents of the open folder. But that sounds like it would waste a lot of resources to do, but I cannot think of any other way it could do that. So I was just wondering…how does that work?

Thanks.

  1. It’s probably a push notification. Rather that the client computer constantly checking, the server sends a message to the client when a change is made.
