Audi Stereo creating ._ versions of file on SD card

[mole]

I'm new to using the SD card with the audi stereo, but following the instructions I've found on the web and various Audi docs - I'm working. Not as I would like but a good starting point.

I'm just testing at the moment so I've copied across a folder with 1 artist with multiple albums in sub folders under it. This seems to work well and the Audi stereo can navigate this fine.

However, when I enter an album folder in the stereo navigation screen it seems to scan the folder for tracks, and then creates a ._ version of the file as well as the original.

for example, if I take the card out of the car and put it back into my laptop the folder looks like this

-rwxrwxrwx  1 mattd  staff      4096 21 Jan 14:31 ._01 Who Did You Think I Was.mp3

these ._ files where not on the card when I put it in. The in stereo navigation system also shows these files and can't play them.

 

why is it creating them ? what are their purpose, am I approaching using the SD card totally wrong.

Do these new created files actually play on the laptop or not at all?

[mole]

no,

I think I figured what was going on with this and it was a small bug in how my mac was setup.

 

all sorted now.
