Dukto is an open source, multi-platform, easy to use file transfer tool designed for LAN use. I have been using it for over an year now to transfer files from my Laptop (running various Linux distros) to my phone and other windows PCs. It's user interface is inspired from the Metro style UI developed by Microsoft and it is consistent across all supported platforms.
(Dukto in Android 4.4.4)
Dukto is developed by Emanuele Colombo, a software developer and engineer. Dukto automatically displays all the devices in your local area network running Dukto and you can select the devices and start transferring files. You can even send a folder to another device.
You can also transfer text snippets like links and notes easily from one device to another.
You can change the default folder to save received files from the settings. You can also change theme color and device name from settings.
Dukto is available for various Linux environments, Windows, Mac OS X, iOS, Android, Blackberry, Windows Phone and Maemo.
Since Dukto doesn't use any pass-codes or encryption, it is recommended to use only on trusted local area networks.
