When u download for your park, its an *.NL2PKG file.
U place it in the main directory where all your other parks are located.Go in the EDITOR > Open file.
When that *.NL2PKG file is completely loaded and error free.
Go in the EDITOR > Extract Package > Hopefully its not Password protected.
Don't forget to save it if u change something.
Then u can look into the park what u need and copy it to your park.
But if u looking for MK1101 there is a download link

He's most likely on about mods, which are not the same as custom objects.
For mod files, you need to put them in the following path:
Install Directory\data
and make sure the names are arranged underneath the files already in the folder.
