Movies that I cannot find are taking up 200 GB on Mac Movies that I cannot find are taking up 200 GB on my Mac. I tried looking for these movies but I cannot find them. I believe that this is being cause by a video editing software I use called "VideoBlend". I think that it creates backups of the videos onto my mac, but I cannot find any them. Not sure what I should do. 

Note: I've searched countless of questions on this site and I was unable to find a solution. 

Update: I also used to manually insert movies into my devices on Itunes. Could there be backup files of these movies?

Update 2: I completely missed out on the fact that my mac has storage space of only 128GB'S. So could this just be an error. If so, is there a way for me to fix it?
