Essentially, WinPE creates a RAM-drive to do stuff on.
To quote the relevant part:
Windows PE reserves memory on the X: drive to unpack the Windows PE files, plus additional temporary file storage, known as scratch space, that can be used by your applications. By default, this is 512MB for PCs with more than 1GB of RAM, otherwise the default is 32MB.
Many thanks David
