Where do download from content management go?

Where do download from content management go?

Hi,

I have sent documents through content management to managed devices. I open the ME MDM app and can see them in content catalog. However, when I download them through Content Catalog, I can't find them on the device. They don't got to My Files or to One drive or Drive, depending on what file storage has been loaded to the machine. They are all Samsung Galaxy Tab A's. 

Help! Where did the files go?
