Where does google chrome store unpacked extensions?

Turns out that unpacked extensions are left in their original locations. Only packed extension get extracted to the places Alex.Piechowski mentioned.

I was able to find luck in:

Non-windows 7:

C:\Documents and Settings\<username>\Local Settings\Application Data\Google\Chrome\User Data\<profile>\Extensions

-or-

Windows 7:

C:\Users\<username>\AppData\Local\Google\Chrome\User Data\<profile>\Extensions

EDIT: You can go to "chrome://version/" (like a url) and it shows your "Profile Path". There you can find an "Extensions" folder which is the one you're looking for.
