So, the 'lot of stuff under applications' is the erroneous duplication of the ios files. When I click on Applications in the above picture ALL I see are Apps, the largest one being 1.15GB and the rest getting smaller all the way down to MB sizes. That's the thing, it shows as 108GB on the outside, yet on 6GB (true total) when looked at from the inside, so to say.
I wouldn't mind if it were just some numerical error, but it actually has taken up 102GB's of memory storage and that seems very unusual. I know that it's the ios files duplication, because when I deleted the iPhone backup a few days ago, the Applications folder went back to 6GB's approximately. As soon as I repeated the iPhone back up, the Applications became bloated again by the invisible invader.
