Off course if its just playback on the computer then you can highlight XX of the video files with the mouse ( left button ) the clock on the highlighted files with the right mouse button and select play, this should then play all the files in the right order.
I mostly do this though it is rare i playback several files, i mostly copy off the SD card a single or 2 files to get the incidents i need for my post processing in pinnacle studio 20 ultimate.
My brain have since my last posted flashed something about Garmin only having the option for 1 minute files, this matter little of there are no overlap on the files you can drop XX of them into any edit tool to output them as one long file, if they do have a overlap "RV" is a good tool to use.
As you can see in my little video above, even with 3 minutes there are room for a lot of them on a 128 Gb memory card, but bulk in this way i can handle just fine.
