I am just getting back into VB.net programming...its been a long time!

I am writing an app that:

1. takes two columns from an excel spreadsheet and puts them into a datagridview. One column is "filename" and the next is "quantity". I have this done so far.
2. searches a server folder and all child folders for the file name listed in each row of the datagridview
3. copies each file that it finds to a folder on the users desktop the amount of times in the quantity column of the datagridview

I would really appreciate any ideas on the best way to accomplish this or code that does this or something similar. Thank you very much!
