Error: move operation failed

I’m trying to move songs to different folders on my SD card and get the error below.

One or more necessary files do not exist or could not be found.

What’s the fix for this?

If this is happening with the beta 5.20 firmware, please report your observations to

If you aren’t using the beta 5.20, give it a try Aeros Firmware 5.2.x

Thank you but the Aeros doesn’t recognize the firmware update on the SD card. I’ve followed the instructions and looked up a video on the process but nothing works.

I just realized that I have a 64gb SD card. That may be the issue.

That was going to be my next question.

It’s definitely the issue.

Get a 32Gb Class 10 SDHC card; new ones come out of the wrapper formatted for use with the Aeros or the BeatBuddy. You don’t need a fancy/expensive/high speed SD card for video cameras. I get the cheap generic ones from Micro Center.
