PSP File Browser Ver 1.00 can open the following file types:

Text (TXT, DB, INI).
Images (for now only PNG)
Music (MP3).

It also has a menu to invoke it by pressing the [Triangle], shows us other options:

System Viewer – View information on the PSP system.
Disk Viewer – View information on space used and available from our memory card.
CPU Clock Changer – To change the frequency of the CPU of the PSP.
Readme – View program information.
(Text is in Japanese), but it is to exit the application.
(Text is in Japanese), but it is to completely exit the application back to the XMB.

Extract and copy the folder to your MS PSPFileBrowser under the path / PSP / GAME.
Open the application from the game menu in the XMB of your PSP.
To open each option by pressing the [Circle] instead of [X], since it is programmed by a Japanese and so is set your PSP.
To return to the previous option or exit a menu option press [X} instead of [Circle].
To access the application menu press [Triangle].
