[jarcher 12]

every night some program saves large 9 Gb files on my hard drive the name of the file is in this format : file08152020000-full.MFI
in a folder named {a683c395-aecb-473a-a0ed-0598f5a4793f} i can find nothing on the net about mfi files thats why I'm here hoping somebody has an answer to what this is and how i stop it.

Do you happen to use a certain MAGIX Film en DVD software per chance? Although I am not familar with it, it seems to be be used for video editing or creating DVD from videos... That would certainly explain the creation of large temporary files of that range!
