If so, is this function also possible to use it in the way to fk up other players' computers by maliciously modifying the file information on a folder??
You mean if someone trys to hack a save? No you cant do that... Does this corrupt files? no... Its called a Game Cache, and i havent looked too far into it but i believe it is pretty limited, but if you do anything with it i suggest adding a "form of protection" by converting everything into it into integers then a real using a higher base than 9, ie X base 80 (possible to do) where you change the numbers 0-9 into 80 unique characters, making it impossible to read to the human eye, but put through a simple function, easy to convert into a normal integer
You can write text documents into someone's w3 folder (and i'm not even sure if you can read it back), but you can't run them through the editor, so you can't perform malicious code.
Ghan has said he has fixed this. Monovertex please confirm this fix. This was only a problem with people that had signatures in the upper levels like not the special members but the respected members.
