duplicated files

[EKAY1953]

using dvd to mobile mp4 format ..saving to desktop then onto a 2tb external drive, delete files from desktop and empty recycle bin, yet in last week(new computer) useage on c drive has gone up from 34 gb to 111gb, did windows explorer right clicked then properties but could not find anywhere on c drive where extra 70gb is, computer has 500gb, but at this rate with hundreds of movies to change to mp4 the c drive will fill quick, obviously dvd fab mobile is copying these files somewhere on my computer but i cannot find.
have h/drive and movies connected to apple tv, absolutely brilliant...

ps even when i copy direct to external h/drive usage on c:drive goes up

It is most probably files in your temp directory.

Turn the "Delete file in temp directory when finished" and you may have to clean up the temp directory yourself of existing files.

Re duplicate files

Not in temp files
do not burn, only changing to mp4 format then copying to ext h/drive
gotta be somewhere, got me knackered
whole c drive has 110gb but when i individually add up all on c drive comes to 42gb
obviously dvd fab is archiving it....but where
