    Ok so im just getting into learning the anatomy of the 3ds NAND Filesystem and i have no what idea on how to tell what the title id's are. for example
    in the

    Nand://data/>Longvariableid</sysdata
    in there is a ton of folders with all kind of names and in each of them is a file simply named 00000000 all with variable sizes see here

    in a example, a small goal i would like to do is backup and restore the mii streetpass plaza savedata.
    how am i supposed to figure out what folders belong to what?
