When you update your Google Chrome browser to its latest version, using its updater module, the old files of the earlier version are always left behind on your disk. This is because, if you wish to roll-back your Chrome to its earlier version, these old files make it possible to do so.
But in most cases, we do not need to roll-back. If you are sure that you will not need to roll-back your Chrome to its earlier version, you can safely remove these duplicate files. In the process you will be able to save around 83 MB of disk space.
To do so, first, via your Folder Options, enable showing of hidden folders. Having done that, navigate to the following location using your Windows explorer:
Here you will see two folder with numbers. These are the folders containing files for that particular version of Chrome. You can safely delete the older version – which obviously ahs the lesser number. Additionally you will also see a old_chrome.exe file. Delete it too.
There is also a tool available that removes these old files automatically.
OldChromeRemover is a simple console program that does the job easily. It basically checks for any redundant versions of Google Chrome left behind by the Chrome updater and removes all except the newest version, when prompted by the user. It supports Chrome ‘Canary’ builds too.
This will allow you to free up valuable disk space.
