Windows 7: Robocopy copying folders from the wrong place

I've set up a back up batch file to copy my Documents, Pictures, Music, and Videos folders from my computer to an external hard drive.
However, while running the Documents backup, it seems to find, the pictures, music, and videos folders all inside the documents folders labelled "My Music", etc.
However, these folders do not exist. When I navigate in explorer to C:\Users\username\Documents\ I cannot find a folder labelled "My Music". When I try to navigate to C:\Users\username\Documents\My Music it tells me that "access is denied". I cannot find them through command line either.
As well, when I try and find the folders on the backup drive, they do not seem to be there either.
I just don't understand where this is coming from.

Hi,

It sounds like you are running foul of junction points. You may need to use the /XJ switch.

Post your BAT code here, and I'll take a look at it for you.

I got around the problem by specifically excluding those folders, but I would like to know why exactly this happened in the first place. What are junction points?

Here's my batch file:


@echo off
::variables
set drive=F:

echo Backing up Documents
ROBOCOPY "C:\Users\*****\Documents" "%drive%\Documents" /MIR /XD "My Music" "My Pictures" "My Videos" /LOG+:"C:\Users\*****\Desktop\log.txt"

echo Backing up Music
ROBOCOPY "C:\Users\*****\Music" "%drive%\Music" /MIR /LOG+:"C:\Users\*****\Desktop\log.txt"

echo Backing up Videos
ROBOCOPY "C:\Users\*****\Videos" "%drive%\Video" /MIR /LOG+:"C:\Users\*****\Desktop\log.txt"

echo Backing up Pictures
ROBOCOPY "C:\Users\*****\Pictures" "%drive%\Pictures" /MIR /LOG+:"C:\Users\*****\Desktop\log.txt"

echo Finished Backup
