NSPsplitty

this is a general purpose tool for splitting or merging files to fit in the 'fat32' file system for all purposes (the name was given to make it obvious that Nintedo Switch files also counts) .

it was made as a more straight forward tool with a graphical interface.

Requirements

it was heavily inspired by the work of AnalogMan151
