Import androidsettings.setting file with ADB

I have an "xxx.setting" XML file exported from an interactive whiteboard running Android. I want to distribute this file to the multiple other interactive whiteboards remotely through ADB and then execute the file with the package com.seewo.easifinder.

The package has the following activities

I have uploaded the settings file to /sdcard/mnt/Documents

If I manually tap on the settings file on the device then I'm prompted to accept that current settings will be overwritten. I have tried to use the application manager. With no luck :) I'm new to ADB and Android so I'm probably just missing something obvious.

am start -n com.seewo.easifinder/.FileRetrieverActivity -d "content:/sdcard/mnt/Documents/xxxxx.setting" 

The result is that the com.seewo.easifinder open file dialog box is launched on screen. But the file specified is not executed. I hope you can point me in the right direction so I can get com.seewo.easifinder to execute the settings file.
