Where does "Voice Recorder" save files to on Samsung S6?

I can't say with absolute certainty where they are on a Samsung S6, but on my Samsung Galaxy Note 3, and I doubt that they change their filesystem layout too much from one device to the next.

I can see them from Windows 10 at:

This PC\SM-N900T\Phone\Sounds\Voice 001.m4a

This PC\SM-N900T\Phone\Sounds\Voice 002.m4a

This PC\SM-N900T\Phone\Sounds\Voice 003.m4a

This PC\SM-N900T\Phone\Sounds\Voice . . .

Obviously the mount point will have a different name through other operating systems, but the path from the mount point will be the same.

As viewed from within the phone itself, they're at:

/storage/emulated/0/Sounds/Voice . . .

If Samsung changes things between devices, well, shame on them. Then this won't help you, but it will at least help people with the same layout as the Galaxy 3.

I found it by searching from within ES File Explorer, and checked for similar names through the Windows mount point. So if it's not in the same place, you can at least search for it that way.
