Sleeper: Copying files invisibly

Hi,

We email files are (5-10 nos) to users for updating data.

I am wondering if it possible to write a program in VB (exe format) that would accomplish the following


1) Program to extract a set of files to different directories such as c:\engg\estimate, d:\program files\engg\database

2) The files being copied should not be visible to the user and should be copied(overwritten, if required) invisibly.

3) The files are send by email from authorised person, so that the attachment can be opened.

Thanks
prakash

Ps: Files to be copied are dat1.org, dat2.org, dat3.org ......
