now i used to have 5gb of unused space in my drive, however ever since i burned my last five dvds, i've begun to lose some memory. i deleted everything i didnt need until the point when there wasnt anything else to delete to free up space to meet the required 4.3 gb empty space in my harddrive. i've concluded that it might be some kind of extra file tht convertxtodvd is creating everytime i successfully or unsuccessfully create a dvd.

now i stopped creating dvd's becuase i only have 2.2 gb left and i dont know what happened the the rest of the memory. i assume that the files are in the Windows folder, but i don't know which one.

what is it and where is it please

much thanks =)
