EditorSettings.assetNamingUsesSpace

public static bool assetNamingUsesSpace;

Description

Controls whether to insert a space before a number in duplicated Asset names.

Unity adds successive numbers to a duplicated asset's name. By default, it adds a space before the number. Set assetNamingUsesSpace to false to turn this behavior off.
