I wanted to personalize my user folders and ran into a little problem

Hello friends i hope you can help me with my problem.

I wanted to personalize my user folders and ran into a little problem. I dont know how, but i managed to make a folder which ill call Double folder under my User folder. The reason im calling it a Double folder is because it contains everything that is under my User folder. This is how it looks like:

User
--Movies
--Music
--Documents
--Double folder
----Movies
----Music
----Documents
----Contacts
----AppData
--Contacts
--AppData

So everything i delete from the Double folder i also delete from the User folder. It basicly acts as a mirror. I cant rename the Double folder nor change its location (but i can do so for all the other folders).

I tried merging the two folders but it just tells me the source and the destination folders are the same. I cant restore the previous versions or copy things because im out of disk space.

Im using Vista 64-bit, hope someone can help, thanks.

Thanks for replying. Yes, you could call it a "shortcut" but it acts as if it were the folder itself. If i delete any folder under the "Double folder", the same folder gets deleted under the "User folder" also. So i cant delete it.

I am not running out of space because of the Double folder (the User folder and the Double folder are the same size), its just that i dont have enough space disk in general to restore the User folder to a previous version (which could be a solution).

Its really a strange problem.

No i didnt use any software, just windows explorer. I made it by renaming an existing folder and changing its location to a folder (Applications) on my other partition. It copied some of the files from the Applications folder to the User folder but i cancelled the process as this was not what i wanted. I moved those files back to the Applications folder on my E: drive and i noticed the "double folder".

Thanks for helping guys, i hope we can resolve this.
