i download a file with bittorent and it downloaded it as a bunch or tda-XXXX.XXX and im not trhat sure how to make them work. if i open the first (its 3 cd) tda on each cd winrar will create a .bin file, can i just burn that image to a disk? also can i put all 3 of them on one dvd instead of a cd because one is over 700mb?
