How do I check the type of sdcard's filesystem?

Question

How to check the type of sdcard\'s filesystem?

For example, in Windows we can see NTFS, FAT32, exFAT, etc.

Thanks in advance.

For custom path, we can use this static method:

public static String getFileSystem(File path){
    try{
        Process mount = Runtime.getRuntime().exec("mount");
        BufferedReader reader = new BufferedReader(new InputStreamReader(mount.getInputStream()));
        mount.waitFor();

        String line;
        while ((line = reader.readLine()) != null) {
            String[] split = line.split("\\s+");
            for (int i = 0; i < split.length - 1; i++){
                if (!split[i].equals("/") && path.getAbsolutePath().startsWith(split[i]))
                    return split[i + 1];
            }
        }
        reader.close();
        mount.destroy();
    }catch(IOException | InterruptedException e){
        e.printStackTrace();
    }
    return null;
}

For example, below code:

Log.i("---", "Filesystem = "+ getFileSystem(Environment.getExternalStorageDirectory()));

will produce this output:

I/---: Filesystem = vfat
