I just looked how I can slim down my home directory and noticed that Chrome's .config directory is unusually big. More than 600 MB in my case.

enter image description here

Most of it is occupied by by the Google Play Music extension (fahmaaghhglfmonjliepjlchgpgfmobi). As you can see in the screenshot, the directory contains a lot of versions which accumulate to a lot of wasted disk space. All other extensions have a maximum of two version (although the reason for this may be that they just don't have a lot of updates).

I don't think it's unreasonable to keep one or two versions in case the newer versions mess things up. But I would like to get rid of most of these unnecessary versions.

Can I just delete them or will Chrome act up? Is there a (non-)secret way to do it from the GUI?


If you have no non-recoverable strings attached to those extensions then I would tell you to uninstall all the versions of the extension (even the latest) and fresh install it. If you have some non-recoverable strings attached then just delete. If Chrome can't find em, Chrome can't run 'em. That's because Chrome doesn't even know what should be there. Look here and here for instructions if you have Windows. The first one is recommended. Looking at your screenshot, the tale is same for Linux. Help for Linux is here. And your screen shot yells Linux. Hope it helps.

    Hm, none of these links look helpful. The second link doesn't work. Yes, I'm on Linux. What is an "attached non-recoverable string"? I guess I'll just do the reinstall way but still it would be nice to know whether the extraneous versions can simply be removed without corrupting the chrome profile. – musiKk Oct 22 '15 at 12:08
  • @musiKk It was a metaphor for something like data or feelings (some people do, I don't) which are attached to that extension or you. Not some computer term. And I tried deleting mine. No problem at all. "Chrome doesn't even know what should be there." It just runs whatever is there. So just delete them. BTW, should I include these explanations in the answer? – Varad Mahashabde Oct 22 '15 at 21:11
