# How do I use a script located not in the Assets folder?

I'm developing several games at once, and they all use the same helper C# class which I have named "Helpers.cs".

This script contains common helper functions.

I'm still making changes to this Helper.cs files quite often, and I have to take care to update this file for all of my projects: If I work at 3 projects as once, I have to make sure I didn't forget to update

Project 1\Assets\Scripts\Helpers.cs
Project 2\Assets\Scripts\Helpers.cs
Project 3\Assets\Scripts\Helpers.cs


This is error prone.

I would like to know if there is a way to have only 1 "Helper.cs", for example in

d:\dev\games\common\Helpers.cs


... and all projects would use this. Then I would only have to update the file once if edit it.

I'm using Windows.

Is this possible?

• Presumably you considered making a symbolic link to this shared folder from inside your assets folder, so to Unity it looks like it's a sub-folder of Assets as usual? That would be more of a Super User question, since it's about working with your OS file system, not game development specific. – DMGregory Jun 6 '20 at 12:27
