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.
Windows (confirmed to work on 7/8/8.1/10)

if you want to use such a tool on any other OS then please use AnalogMan's work; to understand the use of this tool more deeply go read up on his git and check his amazing documentation on how splitting files for the switch works.
short hand to use this tool
browse to file location (split folder or merge file will also be created in the same location)
create a copy or not (leaving it checked is recommended, requires double the storage space of the file selected)
start splitting files or merging them
'Merge files' button will appear only if file '00'is selected (Updates v0.03-a require this)
reports activity for the user to know what's currently happening
select this first before choosing the file to merge (the merge button will appear)
