Hi all. I have a Galaxy 5 and when I opened My Files yesterday I founda .pif file loose among .jpg's and .MP4's and I don't know if it belongs i.e. part of the operational files or something I have inadvertantly loaded, and can be removed. It is named xcykxw.pif . I tried to upload it to my PC via USB but the "open to view files using windows explorer" doesn't show it. I can move it or delete it but thats all. I have no idea if it's needed or not or howmuch space it uses. Any ideas?
