How to get disk capacity and free space of remote computer

I know of psExec tools which you can download from [here][1]


There comes a psinfo.exe from the tools package. The basic usage is in the following manner in powershell/cmd.

However you could have a lot of options with it

Usage: psinfo [[\\computer[,computer[,..] | @file [-u user
[-p psswd]]] [-h] [-s] [-d] [-c [-t delimiter]] [filter]

\\computer Perform the command on the remote computer or computers specified. If you omit the computer name the command runs on the local system, and if you specify a wildcard (\\*), the command runs on all computers in the current domain.

@file Run the command on each computer listed in the text file specified.
-u Specifies optional user name for login to remote computer.
-p Specifies optional password for user name. If you omit this you will be prompted to enter a hidden password.
-h Show list of installed hotfixes.
-s Show list of installed applications.
-d Show disk volume information.
-c Print in CSV format.
-t The default delimiter for the -c option is a comma, but can be overriden with the specified character.

filter Psinfo will only show data for the field matching the filter. e.g. "psinfo service" lists only the service pack field.

Get-PSDrive C | Select-Object @{ E={$_.Used/1GB}; L='Used' }, @{ E={$_.Free/1GB}; L='Free' }

Just one command simple sweet and clean but this only works for local disks

Get-PSDrive

You could still use this command on a remote server by doing a Enter-PSSession -Computername ServerName and then run the Get-PSDrive it will pull the data as if you ran it from the server.

In case you want to check multiple drive letters and/or filter between local and network drives, you can use PowerShell to take advantage of the [Win32_LogicalDisk WMI][1] class. Here's a quick example:

$localVolumes = Get-WMIObject win32_volume;

foreach ($vol in $localVolumes) {
if ($vol.DriveLetter -ne $null ) {
$d = $vol.DriveLetter[0];
if ($vol.DriveType -eq 3) {
Write-Host ("Drive " + $d + " is a Local Drive");
}
elseif ($vol.DriveType -eq 4) {
Write-Host ("Drive" + $d + " is a Network Drive");
}
else {
// ... and so on
}

$drive = Get-PSDrive $d;
Write-Host ("Used space on drive " + $d + ": " + $drive.Used + " bytes. `r`n");
Write-Host ("Free space on drive " + $d + ": " + $drive.Free + " bytes. `r`n");
}
}

I used the above technique to create a Powershell script that checks all drives and send an e-mail alert whenever they go below a user-defined quota. You can get it from [this post][2] on my blog.

PowerShell Fun

Get-WmiObject win32_logicaldisk -Computername <ServerName> -Credential $(get-credential) | Select DeviceID,VolumeName,FreeSpace,Size | where {$_.DeviceID -eq "C:"}

Just found [Get-Volume][1] command, which returns `SizeRemaining`, so something like `(Get-Volume -DriveLetter C).SizeRemaining / (1e+9)` can be used to see remained Gb for disk C. Seems works faster than `Get-WmiObject Win32_LogicalDisk`.

On PowerShell:

"FreeSpace C: " + [math]::Round((Get-Volume -DriveLetter C).SizeRemaining / 1Gb) + " GB"

`"FreeSpace C: {0:n3} GB" -f ((Get-Volume -DriveLetter C).SizeRemaining / 1Gb)`
