Tons of space, well 150Gb on the drive

Whereabouts are the files stored as I have multiple folders in the unpacked one.
Tower of time
Tower of time\Tower of time\cfgtmp
Tower of time\Tower of time\Resources
Tower of time\Tower of time\Tower of time_1
Tower of time\Tower of time\Tower of time_2
Tower of time\Tower of time_1 (this one has data1, data2a.bin files in it)
Tower of time\Tower of time_2 (this has data2b, data3a.bin files in it)
Tower of time\(this has data3.bin and log and session files in it).
What type of directory structure do I need or extra files for each ISO? I have PowerISO installed so making ISO files is easy enough. Just need to know the folder structures and file locations to add them to ISO images and possibly the ISO names to call them for each disk.
