Windows Phone 8 system file structure

Recently, I have been eager to write a WP8 File Manager and read WP8 documents. It seems that it is difficult to implement it in the limited APIs provided by Microsoft, in fact, if you want a file manager, you still want to see the system file structure of WP8 after the revision.

Today, I accidentally opened the WP8 simulator and found that the settings before the simulator were cleared. So I found the emulation installation directory and found several files, flash.480x800. vhd file. Double-click the vhd file and find that the miracle has occurred. The computer has five more drive letters, and the third drive letter is opened with a line of unfamiliar but familiar folders.

I can see whether these folders have the feeling of Windows Mobile. I may just give a look at the content in those folders, which is a bit different from the real machine, because I found it in the real machine of WP8, the path of all the applications you have installed is c: \ data \ Programs \ {guid}, but the things in this simulator are empty. Further exploration is needed. However, the directory c: \ data \ Users \ public should be the directory that you can see in the resource manager by inserting your WP8 mobile phone to the PC. At least I can only see this in lumia920, this storage area does not seem to belong to the SD card, with externalstorage. getexternalstoragedevicesasync () does not seem to be able to read the extended storage area in the 920.

The installation path of the simulator is in c: \ Program Files (x86) \ microsoft sdks \ Windows Phone \ v8.0 \ emulation \ images. If you are interested, check it out, in addition, I want to obtain the method used to obtain the extended storage area on 920. I am a newbie to ask for guidance.
