Taking off from developer Mediumgauge's previous release of PSP Filer v4.4, the latest version 4.5 sports a lot of new features to step up this extremely useful homebrew application.

PSP Filer v4.5 takes care of several bugs tied-in with the .zip and .mp3 files not opening properly under the application. Also, a French and Serbian mode was added, expanding its functionality with other languages. For those of you tech heads interested in checking out the complete changelog, here it is:
