How to find the Directory Junction in C# or VB.net?

Hi,

I am developing a File Search project using .net.

I have a file called "xyz.123" in My Document folder. When I do file search on C: Drive, i will get duplicate files "xyz.123" from 3 more location.

I have copied the files on "C:\Users\admin\Documents".

But the same files appears in the below locations

C:\Documents and Settings\admin\Documents
C:\Documents and Settings\admin\My Documents
C:\Users\admin\Documents
C:\Users\admin\My Documents

How to avoid the duplicate file search in .Net code?

Could any one  help me resolve this issue?

Thanks,
