This was recommended as an addition to our Curated UWP apps list for Windows 10 (Mobile), so I thought it deserved a Flow story of its own. There are plenty of file sharing utilities for Windows 10 devices, but most require passage through the wider Internet - Feem goes directly over Wifi from one computer (or phone) to another. Hence the 'offline' part of the app's full name - sharing here will work even if your broadband is down and it also doesn't use up Internet bandwidth that you might need for other purposes.

From the Store description:

At FeePerfect, we believe the greatest sharing is among WiFi buddies -- family, friends, co-workers who are already on the same local network. No emailing, no fumbling for a special cable, no hunting for a USB stick (won't work for mobile), or impatiently waiting for iTunes or Zune to fire up.  And you don't burn up precious wireless bandwidth! Magic!

Just run Feem (on sender & receiver), choose files to share, select who gets them, click Upload. Bam!

Or choose a chat buddy, and open a session. Simple. Quick. Painless.

Transfer pictures: phone-to-phone, phone-to-computer, or vice versa between iPhone/iPad/iPod, Android, Mac, Windows, Linux, Windows 10, Windows 8 and other Windows Phone 8.1 devices.  Feem doesn't require an active Internet, but the devices must be connected to the same WiFi router or hotspot. You can kiss your USB sticks goodbye. 

Feem v4 on Windows 10 Mobile and on the Desktop - file sharing via Wifi Direct in both directions.

This is free in the Microsoft Store. For your Windows 10 Mobile phones and for your Windows 10 hybrids and laptops. Give it a try and comment, please!

There's lots more info at the Feem web site, too. Looks like this could be a project worth supporting and keeping an eye on.
