Save space disk with Chrome / Chromium (or how not to lose it…)

 Version française disponible

Chrome / Chromium browser has the annoying habit of keeping all of its older versions on the system. Useful to return to the previous version if it fails to install the new one, this history tends to reduce your disk space. When you know that a version is about 80 Mb, it’s a no brainer !

Here is the folders location :

C:\Users\<username>\AppData\Local\Chromium\Application
C:\Users\<username>\AppData\Local\Google\Chrome\Application

C:\Documents and Settings\<username>\Local Settings\Application Data\Chromium\Application
C:\Documents and Settings\<username>\Local Settings\Application Data\Google\Chrome\Application

Then, delete all folders matching old versions (except the latest !). For example, the folder “12.0.742.91” can be removed if the folder “12.0.742.100” exists and corresponds to my current version of Chrome / Chromium.
