I'm wondering is there any way to secure files so that a user, using Windows Explorer cannot delete, or overwrite files.
I have security built into the application which protects the application data . But even with this security, there is nothing to stop a user, who uses the application, coming along with Windows Explorers and deleting a Stock File or overwriting the Customer file with another file of the same name.

Anybody got any ideas on how to protect such files ?

Regards,

Gerard
