Hi there i know this is an old thread and you probably already found a solution for your problem but just in case someone is still interested, the way i approached this was to create my own file browser using [.Net System.IO][1].
Check the [Directory Class][2] , all you need is there.
Start with [Directory.GetCurrentDirectory()][3] to get the **current Directory** path, on **Android** this will give you "/" on **Windows when running in Editor** will give you the path of where your project is.
Store the current Path in a **string** variable like this `var _curPath : String = Directory.GetCurrentDirectory()` then feed that path variable into [Directory.GetDirectories][4] which will return you a list of the paths of all the folders (if any otherwise the length of the list will be **zero** ) in the path you just gave it.
Store those paths in an **string** array i recommend using [Generic Lists][5] instead of unity's built in arrays simply because its easier to manage.
A simplistic example of how to get the folders in the current directory would look something like this
import System.IO ;
import System.Collections.Generic ;
private var _curPath :String ;
private var _curDirectoryFolderPaths : List.<String> = new List.<String>() ;
function GetCurDirFolders () {
_curPath = Directory.GetCurrentDirectory();
for ( folderPath in Directory.GetDirectories( _curPath )) {
try {
_curDirectoryFolderPaths.Add( folderPath );
}catch ( error ) {
Debug.Log( error);
}
}
Debug.Log("Found "+_curDirectoryFolderPaths.Count.ToString() + " Folder(s) in this Directory " );
}
Do the same for [Directory.GetFiles()][6] which will return the paths of the files in that Directory, you can filter files if you need and search only specific file types
All this can be done in UNITY FREE.
Once you got the path for lets say a mp3 audio track for example you can load using Unity's [WWW Class][7].
To access directories and files this way you need to put this on top of you script `import System.IO ;`
To Use [Generic Lists][8] put this at the top of your Script `import System.Collections.Generic ;`
To create a list do this
var _curDirFilePaths : List.<String> = new List.<String>();
Hope this Helps but if you're stuck let me know.
Here's a rough prototype of my DIY File Browser for an Android App im creating.
