List of Mounted Drives on Win32

[Anonymous Monk]

How do I get the list of mounted drives, and their labels, on a Win32 system?

Recent versions of ActivePerl should include Win32API::File which knows how to find all mounted drives and can look up information about drives. It even comes with documentation.

If you have problems with it, let us know. I can probably even whip up a 10-line script to do that for you tomorrow when I'm not rushing to bed. (:

Well, my file copy is taking a while, so here goes:

#!/usr/bin/perl -w

use strict;
use Win32API::File qw(
    getLogicalDrives GetVolumeInformation );

my @drives= getLogicalDrives();
foreach my $d (  @drives  ) {
    my @x= (undef)x7;
    GetVolumeInformation( $d, @x );
    print "$d $x[0] ($x[5])\n";
}

Well, it isn't long on comments and I probably shouldn't recommend calling GetVolumeInformation() that way, but it mostly works for me.

Ok, I looked up some stuff and I found out that Win32::AdminMisc will do what you want if you have a WinNT system. Here's an example(Not tested).


#!/usr/bin/perl -w

use Win32::AdminMisc;

my $drives = GetDrives( DRIVE_FIXED );

print $drives . "\n";


The drive types are:


DRIVE_FIXED      - hard drive
DRIVE_REMOVABLE  - floppy
DRIVE_REMOTE     - network drive
DRIVE_CDROM      - cdrom
DRIVE_RAMDISK    - emulated drive in memory

Some other functions that might help are:


GetDriveType( DRIVE ) - returns the drives type
GetDriveSpace ( DRIVE ) - returns the drives space
GetVolumeInfo ( DRIVE ) - returns hash of drive info
   Element     Desc
   ------------------
   Volume      Volume Label
   Serial      Serial number of drive


I tried this script after installing Win32::AdminMisc and it told me I needed WinNT. So I wrote this one.


#!/usr/bin/perl -w

for( my $i='a'; $i lt 'z'; $i++ )
{
    if ( -e "$i:/" )
    {
        print "Drive $i exists\n";
    }
}


This works under Win98 but it didn't pick up the A: drive because it didn't have any media in it. It also delayed while seeing if the A: drive had something in it. I also don't know how to find the volume label.
I'm hoping you're on a WinNT system, then you're set.
