Alex Rogers made the comment "...AudioMoth won't appear as an external drive...." in another post (https://www.openacousticdevices.info/support/main/comment/da5dd7be-2e9f-325a-8856-fac90ab04e35?postId=5cf009dc58e1c3005e9593e8). Is there a reason for this? I've spent hours in frustration trying to work out why I can't see it in File Explorer, but can on Device Manager. It flashes and configures correctly, even though it's invisible. The only way to see what's on the SD card, including checking the config file, is to remove the card from the device, put it an SD reader, plug that in, check the file, take it out and put it back in the Moth (x20!!). This is a real pain when the computer only has one USB port, and also given the fragility of the AudioMoth itself. Any workaround solutions? (Firmware v1.8.2, Config App v1.9.2, all drivers etc up to date & verified, no issues with admin permissions). Thanks in advance

When you configure, the AudioMoth repeats the received configuration back to the application, and it is checked against what was sent. As long as no warning appears saying that the configuration process failed when you press the 'Configure AudioMoth' button, then the configuration has been successfully transferred to the device. There is no need to check the CONFIG.TXT file on the AudioMoth. Note also that the CONFIG.TXT file is an output file generated when you switch to CUSTOM or DEFAULT. The AudioMoth doesn't read it. It is just there as a reference of the configuration that was set when the WAV files were generated.
The current AudioMoth firmware does not support showing the SD card contents. It's technically possible to do it in the firmware by supporting the USB MSD protocol. However, the low-power microcontroller that AudioMoth uses only supports full-speed USB 2.0 which is just 12 Mbit/s. This means that a 384 kHz recording would only be transferred off the SD card at twice real time e.g. a 60-minute recording would take 30 minutes to copy. The raw speed of the SD card is much faster, and nearly all SD card readers will support much higher transfer rates, so removing the SD card and reading it separately is a better solution.
