"There was a problem with parsing the package".
Am pleased to say that I've been able to solve this problem and all is now working well... I thought I'd just follow up on this thread for the benefit of anybody else experiencing the same issue.
Turns out the problem was a permissions issue... under "Settings" > "Apps" > "Permissions" it's necessary to enable your chosen file manager to do its thing.
Maybe should have been obvious, I suppose, but that error message seems a very poor one to me for such a basic issue. Why not "you don't have the necessary permissions to do this", or something? Or is that just me being used to Microsoft and Apple software?!
