I have only been using the computer for a short time. I am trying to do a manual backup, in doing so I came by the library folder. I see its huge, so I check to see what is taking up all that space. I find a folder called "Containers" with 7.2 GB of space taken up each one. Some, like gamecenter and chess I would prefer to remove from the computer completely, I have no use for them. What is the deal with this folder and how can I manage the space it takes up better. I am going to uninstall blackmagic soon after I run another test.. and see if the container disappears.
