Mass Export Object Editor Data

[defskull]

How do I export the Object Editor data in a large amount of data at once to another map ?
Let's say I want to import 5 custom units I created it via Object Editor -> Units Tab, how do I choose all of these 5 custom units and export them to another map at once ?
What I did so far was File -> Export/Import Unit Settings -> ???
What kind of file type does it obey ?
It says "Warcraft III Unit Data", what extension ?

Also, I want only those 5 custom units will get exported/imported, I don't want all units to be included, how do I filter them ?

The w3u file which is created after using "Export Unit Settings" can easily be modified to remove unwanted units when you import the w3u file.

The things that needs to be changed are:
Tthe number of units to be imported and to simply remove the units

Hope this will help you, otherwise I'll try to answer as many questions as I can
