Exported files will be made accessible to the application via a fuse filesystem that gets mounted at /run/user/$UID/doc/. The filesystem gets mounted both outside and inside the sandbox, but the view inside the sandbox is restricted to just those files that the application is allowed to access. Individual files will appear at /run/user/$UID/doc/$DOC_ID/filename, where $DOC_ID is the ID of the file in the document store. It is returned by the org.freedesktop.portal.Documents.Add() and org.freedesktop.portal.Documents.AddNamed() calls. The permissions that the application has for a document store entry (see org.freedesktop.portal.Documents.GrantPermissions()) are reflected in the POSIX mode bits in the fuse filesystem. The D-Bus interface for the document portal is available under the bus name org.freedesktop.portal.Documents and the object path /org/freedesktop/portal/documents. This documentation describes version 4 of this interface. --> <interface name='org.freedesktop.portal.Documents'> <property name="version" type="u" access="read"/> <!-- GetMountPoint: @path: the path at which the fuse filesystem is mounted Returns the path at which the document store fuse filesystem is mounted.
