You receive a "This folder already contains a file named '<filename>'" message when you copy an NTFS encrypted file to a new location on a Windows XP Service Pack 2-based computer

Consider the following scenario:
  • You have installed file security products on a Microsoft Windows XP Service Pack 2 (SP2)-based computer.
  • You are using drives that are formatted to use the NTFS file system.
  • You copy an NTFS encrypted file to a new location on the computer.
In this scenario, you receive the following message:
This folder already contains a file named 'filename'.

Would you like to replace the existing file

with this one?

modified date and time
You receive this message even though you copied the encrypted file to a folder that does not already contain the encrypted file.
This problem occurs because some file security products disable the NTFS encryption function by using a file system filter driver. The filter driver disables the NTFS encryption function by returning an error on data encryption requests. The Lsasrv.dll module does not correctly handle this error.
