Free Space on all servers for all fixed drives? Done.

A while ago I posted on querying free disk space using WMI and batch.

I wouldn't query free disk space using batch anymore.  The PowerShell script I tweaked and currently use to query free disk space is displayed below.  The script truncates for readability – the rounding methods are commented out if that’s your preference:

# spaceused.ps1
# Lars-UT http://larsrasmussen.blogspot.com
(Get-Date -format 'yyyy-MM-dd hh:mm:ss').ToString() | Out-Default
$outData = @("")
$server = $args[0]
$dataFromServer = Get-WmiObject Win32_Volume -ComputerName $server | Select-Object SystemName,Label,Name,DriveLetter,DriveType,Capacity,Freespace

foreach ($currline in $dataFromServer) {
    if ((-not $currline.name.StartsWith("\\")) -and ($currline.Drivetype -ne 5)) {
        [float]$tempfloatcapacity = [math]::truncate($currline.Capacity/ 1000000000)
    #[float]$tempfloatcapacity = [math]::round(($currline.Capacity/ 1000000000),1)
    add-member -InputObject $currline -MemberType NoteProperty -name Capacity_in_GB -value "$tempfloatcapacity GB"
    
    [float]$tempfloat = ($currline.Freespace / 1000000) / ($currline.Capacity / 1000000)
        $temppercent = [math]::round(($tempfloat * 100),2)
        add-member -InputObject $currline -MemberType NoteProperty -name FreePercent -value "$temppercent %"
        
    [float]$tempfloatfreespace = [math]::truncate($currline.Freespace/ 1000000000)
    #[float]$tempfloatfreespace = [math]::round(($currline.Freespace/ 1000000000),1)
    add-member -InputObject $currline -MemberType NoteProperty -name Freespace_in_GB -value "$tempfloatfreespace GB"
        
    $outData = $outData + $currline
    }
}

$outData | Select-Object SystemName,Label,Name,Capacity_in_GB,Freespace_in_GB,FreePercent | sort-object -property Name | format-table -autosize

To run this against muliple servers just put the server names, one per line, in a text file and save that file. You'll then assign that file to a variable in PowerShell and loop through each line for each server:

PS C:\> $serverlist = Get-Content .\ServerNames-Prod.txt
PS C:\> foreach ($server in $serverlist) { .\spaceused.ps1 $server }

Here’s the pretty output!  Yep, those are sub-second times for querying multiple servers.

Need to document this?  Use Start-Transcript.  I’ve seen auditors use it like so:

PS C:\> $strTimestamp =  [string](Get-Date -format "yyyy-MM-dd_hh-mm")
PS C:\> start-transcript .\ServerSpace-$strTimestamp.txt
PS C:\> foreach ($server in $serverlist) { .\spaceused.ps1 $server }   
PS C:\> Stop-Transcript

Enjoy.

'Copy as Path' - Vista's Best Feature

Arguably one of the best features in Vista for those who live in Explorer with files and directories appears by holding down the Shift key when right-clicking a file or folder:

Copy as Path copies the full path of the file or folder selected as text to the clipboard that can then be pasted in email, in code or at the command line.

The full path gets copied as a plain text string, surrounded by quotes to handle any spaces that might be contained in the path/filename.
