all you do is launch the program, select a path for it to use to move the content of the sd card too then click "Move Files From SD" once that has done you click "Format SD Card" then once that has complete click "Move Files To SD" and finally once that has finished your done.
when you select the path it will store that path in a text file called path.txt which it saves in the same directory as the program so when you launch the program next time that same directory will be selected.
please do not choose a path that already contains files unless you want it to move all of them onto your sd card i recommend creating a new folder i called mine "SWISSTMP" but any name will do.
i hope you find this useful, enjoy..
Update 2:
added option for sdxc cards.
Notes:
if your having issues formatting a sdxc sd card please right click fat32format.exe goto properties and if there is a unblock button under Advanced... then click it then goto Compatibility and tick run as administrator and try again if that still doesnt format the drive to fat32 then goto Computer and format the drive to ntfs and then try again and that should do it.
Extra:
also if your interested here is another program i created:
this will allow you to generate a md5 code for your gamecube iso and gcm files which will be saved as a text file, you will also be able to compare that with a md5 code you paste in or check to see if it is a valid md5 through the gc.dat file from redump (included).
also included a basic md5 generator for use with any file.
Enjoy..
