Drag them into a different folder?
You ask me a question? I thought i was supposed to get some answer. But if i understood correctly you can’t just drag around plugins, because you break them. TMYK
It may or may not work. Some coding packages can not be moved around due to hard coded paths. Some rely on other packages that have to be compiled earlier, which can imply that you are not able to move them around without breaking them.
Moving them around will also make your life a little harder when you have to update them. If you are using something from the Asset Store, you will have to move files around and/or delete them after each update. In the worst case, it will not anymore work if you move it to a different location due to changes made in that package.
If there’s nothing in the plugin’s documentation about needing to be at a specific path, just drag it to wherever you want it and see if it works. Most will, unless, as Dantus says, they have hardcoded a path in the code somewhere.
