In your script, you have a line:
FileName = Dir(CurrDir & "*.*", vbDirectory)
This basically creates a "collection" of information from "CurrDir".
vbDirectory indicates that it is to return "directories or folders in addition
to files with no attributes".
the statement itself returns the first entry in CurrDir.
to loop through the rest of the entries in Currdir,
you use Dir()
So basically, Filename = Dir(CurrDir & "*.*",vbDirectory)
gets the first entry,
Filename = Dir()
loops through the rest of the entries.
BTW: All this can be found using the VBA "help".
hope this helps.
