Identifying Chrome extensions on Chrome OS eating up too much disk space07 Oct 2015 #Chrome OS
I just recently realized I had only 300 MB of free disk space on my Chromebook, when I should have about 8 GB of free disk space. After some investigation, I found that one of my extensions where not deleting its previous versions when it got updated. Here’s how you can detect and fix such an issue.
Type chrome://system into a Chrome tab, scroll down to “user_files” and click the “expand” button for it. This will generate a (quite long) list of files with file size. Then search for the following in in Chrome using alt+f:
Please note, that’s a tab character between “G” and “/home/” in there. You may want to copy (ctrl+c) this from above in order to easily paste it (ctrl+v) into the search field. This will find any occurrences of gigabyte-sized folders and may reveal stuff which is taking up a lot of disk space.
If there is a result which looks something like this;
…you may do a Google search for that last string (

https://chrome.google.com/webstore/detail/ which in this case would result in this link: https://chrome.google.com/webstore/detail/mfaihdlpglflfgpfjcifdjdjcckigekc
So, this reveals we are dealing with a certain extension. Now, to fix this issue, remove that extension from Chrome (chrome://extensions) to see those gigabytes get free’d up.
You can re-install the extension, but perhaps you’ll see it keep eating up your disk space over time. It would be a good idea to notify the developers of the extension in question about the problem so that it will get fixed.
