Batch convert folder & file name

[PepsiCan]

Hi everyone

I'm trying to convert the folder names and file names to a new format. But I can't get it to work. Here is the current folder & filename and what I want to convert them to.

[IF][LOWER][genre][],=,classical,
     [IF][compilation],=,1,1_Classical\[album]\[IFMULTI][disc]-[][track]-[title]_[composer]_[artist]-[disc_total],

I have Windows Vista Home Premium 32 bit and Music Converter 13.4.

I have a game music website which I'm setting up. A lot of people upload music files but they also include sound effect files which are only between 1-45 secs in length which I don't allow because they're not really music....
