foldersname

I need to access the name of an external hard drive from the path name (i.e. the name of the drive that is associated with the F:\ path) . Is this possible?

That's an OS command -- on Windows there's "VOL"

>> !vol
 Volume in drive C is OS 
 Volume Serial Number is ...

MATLAB: How to get drive name

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
