Remote Multi Drive

It provides a faster way to share files than Bluetooth as it works over local network.
The shared content is accessible via web browsers and file managers which supports DAVFS / Webdav.
And there's a built-in File Manager with thumbnail view, bookmarks for folders, and wireless file synchronization between PC and android.
The File Manager can run in java supported browsers as applet and can run in new window with Java Web Start.

Webdav support:
Works with modern popular file managers like Total Commander with webdav plugin, Krusader, Dolphin, and Nautilus(Ubuntu).
Only basic file operations are supported used by file managers.

Usage:
First connect the mobile and other devices to the same local network (Wi-Fi, Hotspot, WLAN) and use the shown IP address in browser after start.
The IP address is not adjustable from Remote Multi Drive.
The IP address is an unique identifier on network and most of cases it is given by a Wi-Fi router when the connection is established.
If no Wi-Fi network available you can use hotspot or Wi-Fi Direct mode.
Wi-Fi Direct allows Android 4.0 (Ice Cream Sandwich) or later devices with the appropriate hardware to connect directly to each other via Wi-Fi.
Most of the mobile internet (2G , 3G, HSPDA connections) are limited and not allow to access your server, but a mobile internet data card or internet stick SIM is works (it is not simple and tested only with a few SIM). If you can install a SIM card to mobile from USB stick it works, but requires maual APN settings depends on SIM provider.

Tips and Tricks:
Webdav and Streaming not works with simple password protection!
If the server not accessible on local network probably the mobile using 3G connection instead of Wi-Fi.
Usually the local address starts with http://192.168. , and in SSL mode the address starts with https://192.168.
Hotspot Wi-Fi mode requires 3G internet connection to work, but it not used on local network by Remote Multi Drive.
The java file manager requires to restart the browser after the network connection interrupted.
Video Streaming example:
Select a video file for sharing and start MX Player on connected device -> Menu -> Network stream and
type the shown network address.

Limitations:
Only the sdcard is writable.
Opera Mini browser unable to connect to the local network (it uses the special proxy server of Opera) !
KitKat does not allow applications to create, modify, or remove files on Removable SD Card.

About the colors of network addresses:
The local Wi-Fi address is white.
The green public address accessible from internet.
The red address not accessible from the internet because the router settings, or the firewall, or the Mobile AP connection is not allow to access the server port.
