How many .jnx (custom) files can I have in the Birdseye folder?

[Stargazer57]

Hi, I'm using the gpsmap 65s already patched. I noticed that if I put more than one jnx file in the Birdseye folder then I'm not allowed to disable the file(s) I don't need. The device loads them altogheter.
What I want is the ability to disable selected files I don't need (like I do with kmz files in the Customaps folder). Is there a way to achieve this?
Thank you
Mike

AFAIK, Birdseye is an "all or nothing" proposition...

I thought so. Thanks
