Unable to delete/copy a file Error 0x80070091

Hi Folks

I have just bought my new PC with Windows 7 Home Premium and installed Windows Mail.

In trying to copy my Window Mail messages folder from my old computer, copying in onto an external hard drive, and I am unable to copy it then onto me new computer.

Temporarily I have changed the location of my Store folder to this hard drive and Windows Mail works and displays all of my saved messages :)

However, when I open Windows Mail I receive this error message

WinMail.exe – Corrupt File
The file or directory J:\Backup\Windows Mail\Local folders\Imported Folder (1)\System ISP\Symantec\Symantec re c0c is corrupt and unreadable. Please run Chkdsk utility’

I have run the Chkdsk utility to no avail. So Tried to delete the file and received the Error 0x80070091

Please can somebody help me out?
