Help Removing GASP Characters

I’m going to use GASP 5.5 as the base for an upcoming project. Before moving forward, I’d like to do a little housecleaning and get rid of any unnecessary characters (i.e. Echo). If I try to delete the Echo folder, the engine crashes. What is the correct process of removing these?

Check the dependencies and remove them before deleting. Right click on the file and check the references viewer.

Another way is to delete the $project/Content/directory from windows.This method may break your project.
