Now comes the tricky part: Obviously, you can delete your own large files - documents, videos, etc but some large files created by the OS or installed by applications may cause problems if removed, depending on what they are. You can then dive into the biggest folder, and see what the biggest sub-folder is, and so on, until you identify what's using up the space.

These will show you the contents of your entire drive, sorted by size. Next, use an app like OmniDiskSweeper, or DaisyDisk. This process may let the OS do some housekeeping, deleting temporary files and some caches. If you're running out of space and can't explain why, then first thing to do is to boot into Safe Mode. I find Apple's breakdown of Storage to be neither reliable nor informative.

Any help will be greatly appreciated.Īnother edit - DaisyDisk also did not show these files: I state once more - the solutions listed here and here did not help at all, if anything worsening the problem (the used space is now 287GB). One snapshot failed to delete entirely - I wonder if this is the one causing the oversized storage? Tmutil listlocalsnapshotdates / |grep 20|while read f do tmutil deletelocalsnapshots $f doneįrom duplicate: tmutil listlocalsnapshots / How can I remove, or even access, this storage space? sudo tmutil listlocalsnapshotdates / |grep 20|while read f do tmutil deletelocalsnapshots $f done I have tried these solutions from the duplicated question and from the Apple forums, and neither of them have worked, even after restarting multiple times. Where can I find out what this is, and how to delete/remove/edit its contents? This problem didn't occur on my other computer (also running Catalina). So all my files take up less than half of my storage space, while this Other takes up nearly the rest! I am unable to work productively (recording videos) as I have no room to store them. I've checked through all my folders, and adding all the items in (from the above window) Documents -> File Browser, as well as every other unique item in the sidebar, comes to roughly 445GB. I've recently gotten a new computer (16' base model with 8GB GPU), and its 500GB of storage had dropped to just 80 when I checked it.
