Windows resource sharing hidden tips WIN7 universal

I want to let my computer open source sharing, and I don't want the average user to click on the network to see the shared files. In fact, you can use the "$" symbol to achieve the purpose of "knowing the shared resource name." The method is as follows:
1, open the resource manager, right click on a folder, select "resource sharing", (take c: \\ temp directory as an example).
2, after the "resource sharing name", add "$" (symbol). (temp$), and finally press OK.
3, other people on the network neighbors can not see the temp folder you shared.
4, you can tell the other party your share name, and then let the other party enter "\\\\ computer name \\ temp $" in the "Start /Execute" to be able to see the shared file. (If the computer is called drj, type \\\\drj\\temp$).
