The easiest way to "sync" documents between devices is to use a Dropbox cloud storage account (www.dropbox.com
). Upload your documents there, then log-in to this Dropbox account in Files Pro on each of your devices, which will automatically sync the current documents stored in Dropbox. You
can tap to view as normal, move, copy, delete etc all from Files Pro.
You can also get Files Pro to download some or all of your Dropbox documents for offline access.
Note that it's not possible to "share" a URL for local upload as you requested. Each device has a unique ID on the network and this cannot be changed i.e. the URL is not editable.
