I made successful Silverlight apps with disk access, see here. I also made a UWP app. I tried to add broad file access without success.

<Capabilities>
    <Capability Name="broadFileSystemAccess" />
</Capabilities>

Severity Code Description Project File Line Skip Status
Error Validation error. error C00CE014:
  App manifest validation error: The app manifest must be valid as per schema: Line 35, Column 6, Reason: The element
  '{}Capability' is unexpected with respect to the content model of the parent element
  '{}Capabilities'.
  Expected: {}DeviceCapability. 2017uwp_run_allow C:UserspiotrDownloads2017uwp_run_allow (1)2017uwp_run_allow2017uwp_run_allowbinARMDebugAppxManifest.xml

So I changed to

<Capabilities>
    <DeviceCapability Name="broadFileSystemAccess" />
</Capabilities>

  [0x80073CF6] Package could not be registered. (Exception from HRESULT: 0x80073CF6) 2017uwp_run_allow

Can only Microsoft register or sign applications with broad file access after looking into source code of app?

I added broadFileSystemAccess capability to manifest but it fails to run. Please see here Error is

Please refer to this document to add the restricted broadFileSystemAccess capability, and the rescap namespace must be added, and is also added to IgnorableNamespaces.

<Package
  ...
  xmlns:rescap="http://schemas.microsoft/appx/manifest/foundation/windows10/restrictedcapabilities"
  IgnorableNamespaces="uap mp rescap">
...
<Capabilities>
    <rescap:Capability Name="broadFileSystemAccess" />
</Capabilities>

After adding the capability, please open the file permissions for your app in Settings >Privacy & security >File system.
