I am constantly irritated by the Windows file copy utility's habit of stopping half way through the process of a copy of multiple files from drive to drive because it decides that a file has an attribute of some sort that it takes a dislike to and it then stops. All of it. With the usual bland one-way dialogue box. And you have no idea where it got to before it all fell over.
I found Y-Copy the other day - does what it says onh the box and copies all the files and then tells you about problem files that it failed to deal with and why.
It is free and available from
File Copy as well as other sites.
