Man, it's been awhile since an update to this was made, I remember Chaos Zero used to include it in his Devhook installers back in the day.  But lo and behold, ufox managed to take on of the best content managers for the psp and made it better.

For those wondering "Why do I need this", it fully displays the contents of your psp, allowing you to view and change the files, as well as the ability to reorder everything to your satisfaction, something you can't do with Windows.  So if you have a full 4gb memstick and are tired of having your most-used homebrew at the bottom of the list, you can do a little reorganizing.  Try it out.
