Re: Can't Play Sims - Low Disk Space

@AtomicDazey  The problem is that the EA App sees the lack of free space on C even though you're trying to install to D.  The workaround is to clear enough space on C, at least temporarily, to allow the App to download Sims 4.

As a side note, it would be best to have at least 25 GB free on C at all times for the overall health of your computer.  Windows can't install a feature update with less than about 20 GB, and temp files will take up space from time to time as well.
