Storage Location for Unpacked Extensions
Extension engine does not explicitly change their location or add a reference to its local paths, they are left in the place where there are selected from in all Operating Systems.
Ex: If i load a unpacked Extension from E:\Chrome Extension
the unpacked Extension is still in the same location
Storage Location for Packed Extensions
Navigate to chrome://version/
and look for Profile Path, it is your default directory and Extensions Folder is where all the extensions, apps, themes
are stored
e.g:
Windows
If my Profile Path is %userprofile%\AppData\Local\Google\Chrome\User Data\Default
then my storage directory is:
C:\Users\<Your_User_Name>\AppData\Local\Google\Chrome\User Data\Default\Extensions
Linux
~/.config/google-chrome/Default/Extensions/
MacOS
~/Library/Application\ Support/Google/Chrome/Default/Extensions
Chromium
~/.config/chromium/Default/Extensions
