How to remove attached scripts files on deleting add-on? My addon is constituted by two files scripts. 
when I push the 'Remove' button , one file stay on the addons folder.



How can I tell blender remove the two python files from the addons directory?
In my __init__.py file

I put this:

if "bpy" in locals():
    import imp
    imp.reload(myScript)


and everything works fine :)
