Where are the sound recorder files in Windows 8.1 ?

Question : Where are the sound recorder recording files in Windows 8.1 ?

Update (Oct 2014)
The current easiest way I know of is  :
open the file explorer
type in the box :
%LocalAppData%\Packages\Microsoft.WindowsSoundRecorder_8wekyb3d8bbwe\LocalState\Indexed\Recordings

Answer : There seems no easy answer to this, but the easiest way I find the sound recorder files is  :

!. Right click the start menu at the bottom left
2. Click 'file explorer'
3. In the search box on the top right of the window that opens (search this PC), type in 'recordings' (the name of the folder is 'recordings')
4. Hopefully the sound recorder file folder will appear, probably at the end of the search as the first item at the top (usually named something like 'C/Users ... etc')

The usual place for the sound recorder recordings folder is something like :
C:\Users\yourusername\AppData\Local\Packages\Microsoft.WindowsSoundRecorder_8wekyb3d8bbwe\LocalState\Indexed 

Comment :
It seems that Microsoft wants to stop people using their OS offline, and wants to entice you to their online products (hence why the 'programs' are now called 'apps'). So with 'programs' you expect in an OS that are standalone, they have now made them awkward to access all aspects of them 'offline' etc. Or so it seems to me.

Also there are 2 'Sound Recorder' programs/apps in Windows 8.1. The very basic one seems to save files in your documents folder but the 'full package' main one doesn't. 

What I did :
I made a folder on the desktop and copy and paste recordings into it.
