Powershell – Get the drive letter of USB drive in PowerShell

powershellusbwmi

I've seen articles in C# and some other languages that explain how to achieve what I'm looking for but I don't know how to convert them.

The following link explains how to get the answer:
How can I get the drive letter of an USB device?
Win32_DiskDrive-> Win32_DiskDriveToDiskPartition -> Win32_DiskPartition -> Win32_LogicalDiskToPartition -> Win32_LogicalDisk
The answer by GEOCHET explains also explains how to achieve the answer but again, not in PowerShell: How to find USB drive letter?

Best Answer

Try:

gwmi win32_diskdrive | ?{$_.interfacetype -eq "USB"} | %{gwmi -Query "ASSOCIATORS OF {Win32_DiskDrive.DeviceID=`"$($_.DeviceID.replace('\','\\'))`"} WHERE AssocClass = Win32_DiskDriveToDiskPartition"} |  %{gwmi -Query "ASSOCIATORS OF {Win32_DiskPartition.DeviceID=`"$($_.DeviceID)`"} WHERE AssocClass = Win32_LogicalDiskToPartition"} | %{$_.deviceid}

Tested with one and more than one USB device plugged-in.

Remove-Item -Recurse -Force some_dir

does indeed work as advertised here.

rm -r -fo some_dir

are shorthand aliases that work too.

As far as I understood it, the -Recurse parameter just doesn't work correctly when you try deleting a filtered set of files recursively. For killing a single dir and everything below it seems to work fine.

Powershell – Determine installed PowerShell version

Use $PSVersionTable.PSVersion to determine the engine version. If the variable does not exist, it is safe to assume the engine is version 1.0.

Note that $Host.Version and (Get-Host).Version are not reliable - they reflect the version of the host only, not the engine. PowerGUI, PowerShellPLUS, etc. are all hosting applications, and they will set the host's version to reflect their product version — which is entirely correct, but not what you're looking for.

PS C:\> $PSVersionTable.PSVersion
