Well, I have a Pocket PC and I do copy music files to it sometimes. (I still prefer hearing it from my SB Live! Digital 5.1) But I still think just pasting the files in the Sync folder and letting ActiveSync do its work is easier.

2-steps:
1. Paste files in Sync folder.
2. Press sync button.

But either way, thanks for the tip, I may just put it to use because you don't have to make so many copies of the files.
