Here’s a simple little df (disk free from Unix) function for PowerShell:
function df ( $Path ) {
if ( !$Path ) { $Path = (Get-Location -PSProvider FileSystem).ProviderPath }
$Drive = (Get-Item $Path).Root -replace "\\"
$Output = Get-WmiObject -Query "select freespace from win32_logicaldisk where deviceid = `'$drive`'"
Write-Output "$($Output.FreeSpace / 1mb) MB"
}
Works nicely as is. I initially thought it needed a default path value for C:\ but I see now that it is taking the path of the current filesystem drive. This can be confusing. For example, change to a shared network drive. Then change to HKLM:. Run the function. You’ll get the value for the network drive. Obviously not a bug just something a user of the function should keep in mind.
I also changed my version to write just the value in bytes so that I can use the value any way I want.
Yeah I was going for the easiest way to discard network drives and PSDrives. You are right that it may not be what a user is expecting. Thanks for the comments, always nice to have you drop by.
