Run Windows Phone 10 Emulator on Compressed Disk

If you are like me, you may have your disk compressed and also try to do some Windows Phone development. I’m starting developing for Windows Phone 10 and have this problem:

The emulator is unable to create a differencing disk

The following screen shot explains that virtual hard disk files must be uncompressed and unencrypted and must not be sparse:

Windows Phone Emulator Error

 

Yes. I do have the whole disk compressed. So as long as I uncompressed the virtual hard disk files, I should be able to run the emulator. But unfortunately, the message box doesn’t tell me what the files are and where they are.

So I searched and found a few results. Most aren’t helpful. They’re for emulators for Windows Phone 8 (e.g. https://msdn.microsoft.com/library/windows/apps/ff626524(v=vs.105).aspx#BKMK_uncompressed). I looked at the paths and uncompress C:\Users\username\AppData\Local\Microsoft\XDE. But I didn’t  find the one for Windows Phone 10.

After a few more searching, I found the location for Windows Phone 10 VH:

C:\Program Files (x86)\Windows Kits\10\Emulation

That’s it. After uncompress both directories, I could debug my app on Windows Phone 10 Emulator.
