Free Disk Space on network share

Hello,

I have a cmd.exe batch script (a one-liner, actually) which returns
the amount of free disk space on each share of a network drive. The
core of the line is dir \\server\share1 | grep free. (Basically the
same as Unix grep. I'm not sure where it came from, but its there).

Anyway, I want to do this in Powershell instead. But Dir is just an
alias for Get-ChildItem and doesn't say anything about free disk
space. I also looked at Get-Item, but System.IO.DirectoryInfo doesn't
seem to be aware of the free space either. Get-WMIObject is out
because the share is on a Netapp. (I got a message saying that the RPC
server isn't available). I don't really want to use WMI anyway since
this information *SHOULD* (IMO) be available to Powershell directly.
And I can't figure out how to run cmd's 'dir' command from Powershell
either.

Anyone have any ideas? Thanks!

Oh... I guess I do have access to "dir":

(cmd /c "dir") -match "bytes free"

But this is pretty lame. There has to be a better way.

Any thoughts?

Try:

# Assumes V: does not already exists

$map = new-Object -com Wscript.Network

$map.MapNetworkDrive("v:","\\$computer\c$")

$fso = new-Object -com Scripting.FileSystemObject

$do = $fso.getdrive("v")

$do.AvailableSpace

$do.TotalSize



# to see everything this object offers

$do |Format-List *



$map.RemoveNetworkDrive("v:")

You don't even need to map the drive first:

$do = $fso.getdrive("\\$computer\c$")

.... will work equally.

Or as a one-liner:

(new-object -com
scripting.filesystemobject).getdrive("\\computer\c$").availablespace
