Im using Macbook 7.1 MAC OS X 10.6.8 Snow Leopard I don't know where i get this exe and pif files, i don't know i think when trying to install windows on it? i don't know.There are almost 18000, they are all in a folder where you can find the Public, Pictures, Videos, etc folder. And also in the drive of Macintosh HD, there are 24000 of this too. Are these exe and pif files important? Will my Mac break if i disposed of this files? I have 219GB space on it and i think those exe and pif files are consuming the space. I think they consumed A LOT because i have a remaining 50GB on it.
