Multiple Library Error - Help!

Hi there,
I was trying to copy-paste my project from one folder to another when something happened. Now when I open the project (from Unity) I get:

Fatal error!

detected multiple library folders within your project"

Did you copy a project into this project? Use "Export Package" to move assets between projects.

You need to remove the following Library folder(s) from your project before you can open it again:

c:/users/documents/myproject/assets/library


When I delete the library folder and open my project directly from Unity it works perfectly fine. BUT, when I try to open it from explorer, it recreates an entire brand new "Library" folder (the one that I have to delete in order to access the project) and all the assets disappears and the project doesn't run. So, my project works only if I start it from unity and just if the library folder is deleted. I have to share this project with another pc, how can I do that? please help me, I'm a step away from a nervous breakdown.

 

I've the same error. In my case, I know I've Library/ within Assets, because I'm using submodules where I split one project into smaller. So I want to disable this warning, how I can do that?

 

You need to have your submodule ONLY contain what can exist somewhere within Assets.

You CANNOT put the entire Unity in a submodule.

You CAN put an entire folder beneath Assets/ in a submodule.

Hare's how we do it:

/Assets/AllTheOtherStuff

/Assets/Submodules

/Assets/Submodules/Submodule1

/Assets/Submodules/Submodule2

and our submodules are mapped to Submodule1 / Submodule2
