I have a folder called maps with a file called Europe_West.tlv

And I have a folder called Zip (but this isn't a compressed/zipped folder) with files

great_britain.postal
great_britainpostal.ver
nederland.postal
nederlandpostal.ver

In TYRE I go File -> New and the map page opens. I do my route, I get it to 'Calculate' then in the map window, I go File -> Save As then in the Save As: dropdown menu choose TomTom Itinerary Files, give it a filename, then I save this to the itn folder on my TomTom. In TomTom menu, it's then Itinerary Planning -> Load Itinerary and choose the file name from the list. I don't go near TomTom Home software. I assume you could just save directly to the itn folder on your SD card.
