Pretty good stuff there.
Just a couple of additions...
Supposedly, the folder name on the USB drive should be named exactly "TeslaCam" (without the quotes, of course), and the capitalization matters.
Once you've used the dashcam for an hour, the "Recent" folder should contain 6 ten minute clips, for an hour running total. The actual length of time of the clips will vary, depending upon how long ago the one hour loop reset.
When you touch the camera icon, it saves the last ten minutes of footage to the "Saved" folder. This is also where Sentry Mode clips are saved.
One way to help prevent corrupted video files or drive corruption is to press the camera icon for ~2 seconds, then wait... the icon should change to just a camera without the dot. That means that the camera is not currently recording to the USB stick, which is the condition you want when you pull the USB drive out; if the camera is currently writing data to the USB stick when you pull the stick out, you could end up with corrupted video files, and corrupted drive directories (fixed with the Tools section of the Properties dialog of the USB stick, if needed, and assuming you're running a flavor of Windows). So make sure you stop the recording process prior to pulling the USB stick out of the USB port to prevent file and drive corruption.
I've also noticed a reduced amount of corrupted files by formatting the disk every time I want to delete the video files instead of just dragging them to the trash. Doing this "resets" the disk directories, and any minor corruption in the directories is fixed, resulting in better results when future video files are created and saved. You just need to make sure that you re-create the "TeslaCam" folder after formatting the drive.
Ever since I started doing both of those things (stopping the recording prior to yanking the USB drive and formatting every time I want to delete the video files) I have had zero corrupted videos.
