Manage your SMB/CIFS Network Shares with CifsManager
XDA forum member f3d0r has coded a small app that allows you to manage your SMB/CIFS network shares on your Android device.
It allows you to conveniently mount/unmount your network accessible file resources and access the files transparently via your favourite Android app (playing music / videos, accessing documents etc.) Settings are stored on your SD card with permissions to write also to your SD card.
Requires root access, and a kernel with CIFS support.
For more information and to download the app, check out the application thread.
