How do i uninstall a plugin?

I installed a plugin a while ago with a ".c2addon" file, but i don't use it anymore, how do i uninstall it? I didn't found it's folder in the C2 plugins folder.

You have to look in this path, where the xxxxxx is your login account:

C:\Users\xxxxxxx\AppData\Roaming\Construct2\plugins

Thank you very much, sir! I found it.
