Utilizing certain commands through it, it would look through the folder & cross check them for errors, repeats, & such... things that could cause issues with those files being played porperly & at the right time... in each of the 'radio' folders... after that, once that was done... then you could sync the whole radio to booting up with the right date/time stamp as your game save/s... accordingly with the SH4 mod set folder you had it dropped into.
I had it added to each of the modded copies of SH4 that I had set up.... each with its own RSM utility. To avoid any cross-contamination issues.
M. M.
p.s.
Taking a bit longer, thanks to Win doing some such with the files explorer... Ugh...
