Powershell script for folder's partition - powershell

Question

I'm trying to create a script which takes a folderpath as an argument and displays how full the partition with the folderpath is (0-100%).
In Linux I know of the df -T $directory command, but I cannot find any way of doing this in powershell. Any tips?

Answer 1

You can approximate the output of df -T by using the following Get-CIMINstance call, which queries WMI/CIM for the information you're requesting. As I'm not a linux expert, I'm not certain what specifically makes df -t a special command. If this output doesn't capture what you need, can you provide some more info?
Get-CimInstance Win32_logicaldisk |  Select-Object SystemName,#{Name=‘Drive Letter‘;Expression={$_.DeviceID}},
        #{Name=‘Drive Label’;Expression={$_.VolumeName}},`
#{Name=‘Size(MB)’;Expression={[int]($_.Size / 1MB)}},`
#{Name=‘FreeSpace%’;Expression={[math]::Round($_.FreeSpace / $_.Size,2)*100}} | ft
> SystemName Drive Letter Drive Label Size(MB) FreeSpace%

Ok, I created a function called df using this code below. You can provide a directory with -t to get the statistics for that particular partition. Otherwise, if run without a param it will give us the disk statistics for the current disk.
Function df {
Param
(
# Param1 help description
[Parameter(ValueFromPipeline=$true,
ValueFromPipelineByPropertyName=$true,
Position=0)]
[Alias("t")]
$directory = (get-item (get-location)))
if ($PSBoundParameters.Count -ne 0){$directory = dget-item $directory}
$root = $directory.Root.Name -replace '\\','%'
Get-CimInstance Win32_logicaldisk -Filter ("DeviceID like '$root%'")| Select-Object SystemName,#{Name=‘Drive Letter‘;Expression={$_.DeviceID}},
#{Name=‘Drive Label’;Expression={$_.VolumeName}},`
#{Name=‘Size(MB)’;Expression={"{0:N0}" -f [int]($_.Size / 1MB)}},`
#{Name=‘FreeSpace%’;Expression={[math]::Round($_.FreeSpace / $_.Size,2)*100}} | ft
}
df -t .\SampleDir
>SystemName Drive Letter Drive Label Size(MB) FreeSpace%
