disk usage in windows

kitsonrp has asked for the wisdom of the Perl Monks concerning the following question:

hi,

Does anyone know of a way to find disk partition infor mation for windows. I need an efficient way to find:

1. total space on drive c:

2. Amount used on drive c:

Due to the overhead on the system I don't want to total each file

Thanks.

I have no idea, but a quick CPAN search for win32 disk space yielded the following module: Win32::DriveInfo. You might want to look through Win32::API, since I'm pretty sure there is a Win32 API call to get that info... Update: Yeah, its `GetDiskFreeSpace` or `GetDiskFreeSpaceEx` -- 3dan	[reply]

Use the FileSystemObject, a wrapper around the API. It runs almost instantaneously. It's installed if you've got Windows Script Host installed. Here's an example: `#!perl use warnings; use strict; use Win32::OLE; my $fs = Win32::OLE->CreateObject('Scripting.FileSystemObject'); my $d = $fs->GetDrive('c:'); print $d->{TotalSize}, " total\n"; print $d->{FreeSpace}, " free\n"; print $d->{AvailableSpace}, " available\n"; print $d->{TotalSize} - $d->{FreeSpace}, " used\n"; __END__ Output on my system: 4446814208 total 2482372608 free 2482372608 available 1964441600 used` [download]	[reply] [d/l]

Thanks jsprat, it saves me a lot of run-time! I would ++ (but I spent them all)	[reply]

Hi i suggest you dont use perl for this. Nobody kill me. Just that inthis case for windows 2000 and XP (not NT) WMI windows managements instrumentation is the best bet. Try a search on WMI regards chimni	[reply]
