Macbook showing unusual storage uses I'm using macbook retina mid 2014 with storage capacity 128GB. When i check my storage About This Mac > Storage, its showing uses of movies occupying 3.96GB. I check all folders individually but i can't find a single video file.

And also why the "other" section occupying 56.04 GB of storage.
Here is the screenshot.
When I have run across puzzling lack of space on my Macs I have used the freeware OmniDiskSweeper that catalogs the disk and sorts by size. there are others out there that do similar things, this article talks about three.

One of those should help you discover, in greater detail, what is consuming the space on your Mac.
