My computer is running slow and almost out of HD space. Says 70 gbs of other data. I have no clue what it is. I have a 320 gb 2011 macbook pro 13. I have 80gbs of movies(digital copies I get with my blu rays), 8 gbs of pictures, 1 gb of documents and 115 gbs of music. It says 60gbs of other files? I checked out how much of that is appliciations and its 25gbs. Then the OS has to be a couple gbs but can't be 35 !!! That is insane. I watch netflix and comcast stream all the time and wonder if that is the rest of the data? Is there a way to delete it?
