Copying a folder containing some files and subdirectories to an empty folder
on a different partition using Vista Windows Explorer sometimes I get errors
"There is already a file with the same name in this location ...".

The problem seems to be related to permissions.

Steps to reproduce:
Create a folder \test with a file test.txt and a subdirectory \db.
Using SQL Server Management Studio create a new SQL Server 2005 SP1 database
with full-text catalog in the \db folder.


Shut down all SQL Server processes.
Copy \test to an empty folder.
Click continue when Explorer asks for admin permission.
Explorer complains that test.txt already exists.
