Windows WinJS App系统访问

Question

I would like to create my own tool to sort photos and videos from anywhere in the file system, sorting and changing names, and stuff like that (basically a sorting tool with custom sort parameters).

Since windows store apps are easy to distribute I think it could be a nice place to develop it.
while I have nothing against C# or VB that i guess it could be easily done with it, I would like to try the HTML/CSS/JS apps of the windows store.
I'm not looking for profit on this, since is aimed for my family .

And I don't really know what kind of access to the file system do these apps have.

I consider a store app because of the universal model, if necessary I could port it to the phones too, the other option I'm considering is just to use ironpython and make it full Desktop.

With UWP apps you don't have the full access to the system files. Of course you get one to the working folder of your app - LocalFolder . By using suitable Capabilities you can be granted an access to specified libraries like: Music , Photos , Videos and more, known as KnownFolders . Additionally you can widely access removable devices. To prevent access violation to work on files in KnownFolders you have to use a special broker, which will grant privileges to your app.

The full list of access permitions you will find at MSDN .
