Thanks to a tip from reader Torch (kudos!), we're letting you guys know that developer mediumgauge has recently finished work on PSP Filer version 4.7.

This organizer application's very first release for this 2008 carries a couple of new innovations, including the feature that mutes sound when your PSP's CPU is busy. Here's the rest of the changelog:

* mutes sound while CPU is busy.
* added a feature to create a directory in copy screen.
* added a feature to access RAR archive file. (read-only)

Full installation and usage instructions for PSP Filer version 4.7 are available in the file bundle's readme. Also be sure to load this application's proper file version depending on your PSP's firmware.
