Copy & Paste Folder Tip in Windows

I used to copy a lot of folders from one machine to another machine. However, I misunderstood the overwrite feature in windows. This is to share my stupidity.

Consider the following scenario:

Folder A (Machine X)
File 1
File 2

Folder A (Machine Y)
File 3
File 4

Assuming machine X and Y are connected in the network, I want to copy File 1 and File 2 from Machine X to Machine Y and the end-result will be something like:

Folder A (Machine Y)
File 1
File 2
File 3
File 4

So I right click and “Copy” Folder A in Machine X and “Paste” it to Machine Y. A message box appears as below asking whether I want to overwrite (my assumption) the existing Folder A.



What I really need to do is just click “Yes”, it will MERGE the Folder A in Machine Y without removing the existing File 3 and File 4. Before that, I used to click "No" because I thought File 3 and File 4 will be gone. So what I did is manually copy File 1 and File 2 to the Folder A in Machine Y. If I have 10 folders, I actually manually do it 10 times! You see how stupid I am!

Look back to the message carefully (which I ignore all the while), it actually explains it very clear - "Do you want to MERGE this folder". Ya, Windows XP doesn't explain that and probably this is the reason I thought all the while is the overwriting feature if we replace the folder. No, it is the merge feature.
