Where does the new Microsoft Edge (Chromium) install extensions on the Windows machine

By default, We could visit the installed extensions from the following folder:

 %userprofile%\AppData\Local\Microsoft\Edge\User Data\Default\Extensions

or

C:\Users\username\AppData\Local\Microsoft\Edge\User Data\Default\Extensions

[Note] The installed extension folder name might be is not the extension name, it is the extension ID property (Click the "Details" link in the installed Extensions (edge://extensions/)).

For example: Using the New Microsoft Edge install Edge Translate extension, the extension folder name is "bfdogplmndidlpjfhoijckpakkdjkkil".

[Note] If you are using Microsoft Edge Beta/Dev/Can version, the extensions folder path should be based on the Edge version, like this:

 %userprofile%\AppData\Local\Microsoft\Edge Beta\User Data\Default\Extensions

[Note] If you add multiple profiles, we could visit the extension from the related Profile folder, like this (the {number} starting from 1):

C:\Users\username\AppData\Local\Microsoft\Edge\User Data\Profile {number}\Extensions
