If you were around a couple of years ago, then you may have head of a homebrew called CyanogenPSP. This homebrew provided your PSP with an Android-esque interface and it had numerous features including:
A launcher for homebrew, PS1 games and PSP games
A picture viewer and music playerCMFileManager PSP is probably the best PSP file manager out there even though it’s a little late to the game
Support for custom wallpapers and fonts among other features
While it included a lot of features and looked quite nice, its developer, Joel16, says that its code was quite a mess and the file manager barely worked. To ‘remedy’ this, he decided to give the PSP scene one final contribution and that was the release of CMFileManagerPSP which, obviously, contains much better coding than CyanogenPSP as Joel16 has learned a lot during his Computer Engineering course.
CMFileManagerPSP looks very similar to NXShell and provides the following features:
Ability to copy/move/paste/delete and rename files and folders. You may also create folders
Option to browse flash0 and flash1 although you should be careful not to mess around with anything here unless you know what you’re doing
An image viewer (which didn’t work properly on the images I tried)
A dark theme although I prefer the lighter one
It can launch ISOs and homebrew
Many other features including auto USB mounting and a nice looking status bar
