inKa File Manager
Here's a File Manager that is as graphically awesome as your HTC Droid. Use this over any other File Manager to get Copy, Paste, Move and all of the other functions you'd expect, but with the easiest-to-navigate interface of any file manager on the market. Even pick a 'home' directory the app will always start in (like 'Downloads') so you're always 1 click away from your favorite location. Upgrade to inKa File Manager Pro to rid yourself of the minimalist ads.
