MATLAB: How to get drive name

driveenumerationfilefilesystemusb

I am trying to get the drive name, not just the drive letter. For example, I have my 'C' drive and it is called 'OSDisk'. Given I know the drive I want to find the name of ('C'), what function should I call to get the name 'OSDisk'?

Best Answer

On Windows this function works with my local drives
>> DriveName( 'C' )
ans =
    'OSDisk'
>> DriveName( 'D' )
ans =
    'DATA'
>>
where
function    drive_name = DriveName( drive_letter ) 
    cmd_str = sprintf( 'dir %s:\\zzzzzz', drive_letter );
    [~,msg] = system( cmd_str );
    cac = strsplit( msg, '\n' );
    has = contains( cac, 'Volume in drive');
    drive_name = regexp( cac{has}, '(?<= is ).+$', 'match', 'once' );
end
I'm sure there are more robust solutions, see e.g. GetVolumeInformationA function
A bit better
function    drive_name = DriveName( drive_letter ) 
    cmd_str = sprintf( 'vol %s:', drive_letter );
    [~,msg] = system( cmd_str );
    cac = strsplit( msg, '\n' );
    drive_name = regexp( cac{1}, '(?<= is ).+$', 'match', 'once' );
end
