Im not familiar with the Network tree and how to delete entries within it.
I have many duplicate entries, I think because I have set up several of the same folder on other drives. For example on my PC I have a Music folder, a Movies folder and many other such common folders that I have set up for various drives so now in the Network tree I get Movies/Movies2/Movies3 etc. How do I eliminate the redundant entries?

When I click on Movies3 in the Network tree for example it tells me "the location is unavailable, if this is located on this PC...It might need to be deleted" Except a right click does not provide that option. Cant figure how to delete it.
