What is the best file manager app for Android

[HarryStamper]

I am thinking of getting the Bionic. I have been on BB for the past year. Besides email, texting, internet...
I like to use the device as place to store documents. As a programmer, I like to store my notes and code snippets on the phone. I plan to email the doc to myself, then save the attachment to a folder somewhere. Then when I need to review something I will always have it with me. I ride the train daily so I often look at these notes when I am on a project,
Is there a file manager app that is considered the best on the Android Market.
Thanks for your help.

I've always been a fan of ES File Explorer.

The phone has one built in. It's pretty good.

I used to use Astro, but I use ES File Explorer.
It works well. It also has alot of features for my DropBox account, that the official DropBox app does not have.
