New Person Looking for suggestions/directions and scripts

Hello all,
 
I am a newbie to the scripting lingo and concept.  I was hoping some one would be able to point in the direction that reflects my objective:
 
We are migrating roughly 500 user's to exchange 2010 from 2003.  We were told that the .ost files will need to be deleted before the migration can take place.  We have a boat load of users that are known as "floaters" (they bounce from computer to computer).  I am looking for a script that will delete all .ost file(s) as local admin.  I have a basic understanding of how to delete a file using a script, but I'm not sure of how to tell it to look in all the conventional location(s) of the various user profiles that may reside on the hard drive.
 
Any help would be greatly appreciated for I am not looking forward to doing this manually. (I apologize in advance if I posted this in the wrong section/area)
 
Sincerely,
Tony

I found what I was looking for.  I basically pieced a few of scripts together to get what I needed.
