Thanks steje. That makes sense. I've used SAMBA to view and manage files between Windows, Linux, and even Mac machines for years. Macs, of course, also use Airplane.
In a bit of surfing since reading your reply I've found some options.
From a forum —
. . . if you want to share the resources you have to install the samba application (Server); it does however already have a Samba client application (Network Shares).
That's a good start.
From another forum —
First you need an sbm app for your phone like Samba. Using Samba you can share and browse your phone on your network. Basically you'll be able to browse it over wifi by going to \\android\sdcard . . . Then map a network drive to the shared network resource. For me, I made a "W:" drive for my wifi syncing, and mapped it to \\android\sdcard.
On the Google play
site there are a lot of SAMBA apps, which I have not tried to use or have any first hand knowledge about. One, Samba Filesharing, creates a WiFi server —
* Samba filesharing server for Android.
* Your Android device becomes visible to other Windows (& SMB compatible) computers on your network.
* The 'external' storage in your Android device is accessible as a network shared folder.
* Copy files and folders to and from your Android device using drag and drop.
From a blog —
You know how when you connect your phone to your computer, you have to connect it via a cable and have to mount the directory before being able to transfer files back and forth? Well, Samba Filesharing allows you to transfer files wirelessly as long as your computer and phone are connected to the same network. No more having to connect the cable anytime you want to do a quick file transfer . . . [on some Androids] there is a built in feature called Wifi-Direct which does the same thing as this app [Samba Filesharing]. You can find it in the settings
So there are some options to make the files on an Android cell phone SD card visible and manageable using D-Opus.
