Desktop/folder problem


Beta member
I am not so good so I would appreciate if you help me.
Mostly times when I open my Torrent download folder (250gB) my comp freeze for few moments. This is the bigest folder and it takes about 95% of my memory. I god only 1 partition (Local disc C:) and I am curious what is the problem. After opening Torrentfolder, that don't happen every time but when i open the 2nd biggest folder simpsons 28gB window open saying it is error.
then it close my folder and this is next what come - screenshot ->
