Upgrade Key, etc. File

[haroldef]

Hi,

I am using Win 7 and have filepro in c:\appl\filepro.  When one has to 
send an email with an attached upgrade to a program used in 
filepro--when the receiver of the update is unskilled with 
computers---What is the easiest way to upgrade files in, for example, 
filepro\mac\key or filepro\mac\onbydate.prc, etc.

I had one thought, and tried it out, which was to send myself an email 
that had an attachment which I renamed to:
C:\appl\filepro\mac\keytest.

When I received the email the attachment name was 
c:\appl\filepro\mac\keytest, so I right clicked and did a save as.

The attachment went to c:\appl\filepro\mac and had the name 
c--appl-filepro-mac-keytest.

This actually worked when I changed the name from 
c--appl-filepro-mac-keytest to just key.  Of course I renamed the key 
file to something like keyhold, so that if the upgrade failed, I could 
just rename keyhold to key and be back in business.

What is the simplest way to upgrade an unskilled user?  Any one have a 
better way?

Maybe I can have the receiver rename the key file to keyhold, and have 
the update end in just mac\key, so the receiver could just eliminate 
everything before the word key.
