    I am having the following problem. I bought a mac about a month ago, 250 GB hard drive. I have not downloaded any significant amount of software or videos as far as I can think of. However, this morning it said it had 3 GB left. This was hard to believe - I assume if Macs typically filled up after 1 month of use, no one would buy them.

    The messages are
    1) Yellow "!" triangle: "Your disk is almost full; Save space by optimizing storage" (close / manage)
    2) Dropbox symbol: "Your hard drive space is low; Dropbox can't sync until you free some disk space on your computer."

    Under apple icon > about this mac > storage, it says "898.5 MG available of 250.79 GB" ... "251 GB flash storage."

    Its specs according to "about this mac" are: MacBook Air, 13" 2017; Processor: 1.8 GHz Intel Core i5; Memory: 8 GB 1600 MHz DDR3; Startup Disk: Macintosh HD; Graphics: Intel HD Graphics 6000 1536 MB.

    When I click "manage", it shows the following disk usage stats:
    Applications: 6.53 GB
    Documents: 7.69 GB
    iBooks: 0
    iCloud Drive: 204.66 GB
    iOS Files: 0
    iTunes: 0
    Mail: 0
    Messages: 0
    Music Creation: 2.55 GB
    Photos: 0
    Other Users: 582 KB
    System: 22.71 GB

    It would seem that the problem is the iCloud Drive. So I click on it and "open iCloud preferences."
    This leads to a window that says "755.4 MB of 5 GB used."
    Below that, there is a bar that says "4.26 GB" and it is about 20% full.

    So ... which is it, is my iCloud Drive storing 4.26 GB or is it 204.66 GB? What is using up the 250 GB? Do I really have 250 GB or is it somehow much less?

    By the way, my dropbox account online says: "Using 6.53 GB of 1.01 TB"

    So, I can't figure out what is taking up all this space.

    Thanks for any help you can give.

    Update: I looked at some links and ended up doing this from Terminal:

    sudo du -d 1 -x -c -g
    (repeating to find the directory with the problem)
    ls -la | more

    This showed a single 200GB+ file on the Desktop called
    205394403328 Mar 29 17:49 .Sub4.1.py.swp

    Apparently, this file does not show up in Finder searches, or else I am doing the search wrong.

    Do you have any Python apps installed? I'm pretty sure that's a Python swap file. You can delete it, though.

    Also, do you have Time Machine on?
    Could the "local snapshots" be eating up disk space?

    Try DiskWave (small and free) from here:
    DiskWave Homepage

    Just download it and open it.
    Go to preferences and set it up so that normally-invisible files will be visible.
    Then, open DiskWave's window.
    You should see what to do next (it's that easy to use).
