Great news :-).We tested the daily folder option in a demo version for the last two month and it works very well. We recorded more than 100,000 files on a 128 Gb SD card without any problems.

Great news. Thanks for the very efficient support. We will be very happy to test it. I will send you a mail with details.

Hi Alex, Ecellent. If you have any pre-version please let me know. We are working on several project of using AudioMoth for long term monitoring for bats, birds and whales. We successfully tested SD-card up to 512 Gb, using solar power and large batteries and developed an external weather proof microphone to be used in marine condition. Morten

Hi Alex, Thanks for the reply. If you do some coding for writing sub-directories we will be happy to test a first version. I will apply 15 modified AudioMoth on marine buoys in the Baltic Sea in March and need a setup for long-term use.
