How to make a file sharing service with remote offices?

Question

Computer networks

Welcome all!
Tell me on what to make a file hosting service, the task is as follows:

• in the head office there is a person who corrects the schemes (visio, modus)
  
• remote offices need access to up-to-date schemes (for reading)
  

On ftp it is "difficult" for people to download first, then run it. I considered the WebDAV option, launched it on WS2012, but it even slows down terribly in LAN. Whether there is a sense on a linukha to try to lift (whether will work quicker)? Or maybe there is an alternative?

Answer 1

BitTorrent Sync , interesting and fast.
rsync , simple and unpretentious.
samba , flexible and complex.
Or you can Dropbox or Google Drive, they are just a little more commercial.

Answer 2

DFS

Answer 3

in general, while I stopped at BitTorrent Sync , I twitched from the speed of my eyes, everything is instantly updated. The only downside is the cost. But like free functionality should be enough.
