Deleting Files Releases No Disk Space
And no, my Time Machine is off the entire time. (I have looked up various articles at this point and all seem to say the solution is to turn off Time Machine - but I can't execute that if mine wasn't on in the first place.)
The issue is basically the exact same as this article below:
Deleting files doesn't free up storage space
I use I have deleted over 50 GB of files and emptied Trash but still I get the dreaded "Your startup disk is almost full" message.
That being said, this happened after my Parallels Desktop Windows 7 virtual machine took up too many space on my computer, causing me to delete the file - which was approximately 30 GB. I never got any space back, and I have tried reinstalling the virtual machine multiple times to no avail. At first the VM wouldn't even bother installing because the moment it creates one it stops itself and says there isn't sufficient disk space. Today the VM tried installing itself - what's weird is that Parallels say that required space is 20GB but Disk Utility says I have less than that. Nevertheless, the installation progress got stuck at 70% and deleting other files didn't decrease disk space either, and I had to delete the virtual machine once more, not decreasing disk space again.
This has caused me great despair and I would really like to know what the problem is and how to solve it. Thank you.
