Verify the type of files before merging

In order to properly use this function, these features must be the same type and Schema. If the Schema is different for one or more of the feature files, the user can edit check and edit these to match in Schema Editor.
 

If the shapefile type is different between files, the user can use the Create Features From Existing Features function to create SHP types that match.
