Google Chrome does get updated very often, and it does it so flawlessly that most of us aren’t aware of the fact that it keeps both its old and newer version files intact. What I meant to say that whenever Google Chrome gets updated it does so without replacing the older files. If you really want to check it out yourself you can do so by enabling show hidden files from Control Panel > Folder Options > View tab, and then opening the following location in your Windows:
On Windows XP: C:\Documents and Settings\
\Local Settings\Application Data\Google\Chrome\Application
On Windows Vista/7: C:\Users\
If you move to the above mentioned location you’ll see two versions of Google Chrome one old and one new. As you can see there are two executable files for chrome one old as old_chrome and the newer one as chrome.Now to remove older chrome files with nothing just a simple console tool you can use OldChromeRemover which automatically detects and deletes obsolete version of Google Chrome.
All you have to do is press “Y” key on your keyboard.
