What is the best app for transporting video files to my HTC?

Hi everyone. I'm an Android noob basically and am looking for an app that'll help me transport large movie files to my HTC. I am also looking for an app that can play videos well.

First off, what kind of HTC do you have?

But here's the way to do it:

Plug your phone to your computer via USB.
Select Disk drive connection on your phone
Drag and Drop your videos from your computer to the phone (this may take a while with large files)
Open and play the videos with mVideoPlayer

This should do the trick. Be warned, however, that depending on your phone not all video formats can be played (like .mov .avi etc.)
