I'm going through my clothes meshes for clean up with. So I open this mesh meshaikeacamisa on SimPE to check the polygons, when I noticed it seems to have a lot of files and stuff. It doesn't look like the normal aikea guinea meshes I have and I have no idea where it came from. Kust wondering what it is.

Looks to be a renamed file of the kind that occasionally packages alongside sims (for some strange reason, possibly if a player uses a file that contains edited maxis accessories, but I'm not sure).

It has been 'shipped around' in sim files for a long while, under various names, sometimes just looking like a string of digits, other times renamed. It's usually around 6 mb in size, so if you find other weird, CAS-related files with that size, you probably want to check those, too.

It's not a mesh file you need (it can even cause trouble), and it can be deleted.

Oh so it's similar to that gibberish fike that was affecting elder males in Cas I remember throwing that out years ago.

Yep, it looks to be the same.
