Danganronpa V3 Filetype Help

[Shinigami_Guntz]

So i recently was able to buy Danganronpa V3 and I want to attempt to get the rest of the Virtual World Sprites and Things for characters but when i extract the files using the cpk script for quick bms (the version that lets files over 4gb be extracted) it spits out all the games files as a .spc file and my computer seems to read them as certificate files. I'm not sure how to go about getting these files extracted or how to even go about trying to open them. I could really use some help if possible, i'm trying to rip mainly Kiibo's Virtual World sprites and a few other things here and there.
