All of a sudden I've run out of space. On my 250GB hard drive, 236GB is used up with only 13GB free.

I used Finder to find big files. Nothing significant.

I used tools like Disk Inventory X, OmniDiskSweeper and Purple Tree, but according to them I've only used up 40GB.

So somehow 200GB is used up, but I can't see where.

Time Machine isn't running (and never has). The disk has no partitions.

  • Great suggestion! I just tried DaisyDisk. When I scanned as an admin, I found 187GB in the hidden ".DocumentsRevisons-V100" folder. It's the Autosave version that it seems OS X has started doing. Why did this happen? What's the best way to deal with it? It looks like some people just delete these files, but how do I prevent it in the future? – Nathaniel S Jun 8 '16 at 15:01

I scanned my drive with DaisyDisk, and as an administrator. (Instructions) I found 187GB in the hidden ".DocumentsRevisons-V100" folder. These are document versions which the OS autosaves (more info). It appears to be from documents primarily from the app Sketch.

Here's how I removed the files.

  • Open Terminal
  • Paste defaults write com.apple.finder AppleShowAllFiles YES (This makes all hidden files visible)
  • Relaunch Finder. You can hold down "Option" and then right click Finder. Click Relaunch.
  • Look within the folder Macintosh HD/.DocumentRevisions-V100/ (For me there were a number of underlining folders with lots of files within.)
  • Delete the folders and files within.
  • Empty the Trash
  • In Terminal paste defaults write com.apple.finder AppleShowAllFiles NO . This makes hidden files hidden again.
  • Relaunch Finder again. Click the System Apple top left, then "About this Mac" and then "Storage." Breathe a sigh of relief.

Here's some articles I referred to:


I did it the old fashioned way and created a cron job.

`#!/usr/bin/env bash 
 export DIRECTORY="/.DocumentRevisions-V100/.cs/ChunkStorage"
 if [ -d "$DIRECTORY" ]; then
    # Delete file
    rm -rf /.DocumentRevisions-V100/.cs/ChunkStorage/*

With a cron job to remove at noon.

crontab -e contents 0 12 * * * /bin/bash /SCRIPTS/remove_chunkstorage_sketch.sh

  • Do you mind taking a minute and explaining what your code does and how it answers the question? Some people will not understand what ChunkStorage is. – ʀ2ᴅ2 Nov 26 '18 at 18:13
  • 1) Checks for the folder in question (the one that stores the versions) 2) if folder exists, it empties the folder with the versions. I created a cron job to run this every day at noon. – amatusko Nov 27 '18 at 22:50
  • I'd never run such a script. Any script with rm and * in it is begging for disaster. A extra blank in the wrong place will be a disaster. – historystamp Dec 24 '18 at 0:11
