I'm struggling trying to grab the latest volume/Drive using PowerShell

I have a result of a PowerShell look like this 

PS C:\Users\me> Get-WMIObject Win32_Volume | select Name

Name
----
C:\
D:\
E:\
\\?\Volume{021a6bbd-0b97-4973-824a-7c635e362f09}\
\\?\Volume{bae1c1d6-59c3-44b1-9360-b7d3101c0e92}\


PS C:\Users\me>

If I want to access just this

E:

How can I filter out to :\ with the highest alphabetical order ?

I've been trying so many options using Select-String, but seems to get worse result.

The ones you want don't start with "\\". The drive letters may be returned in any order, so you need to sort them and take the last one:

Get-WMIObject Win32_Volume | Where-Object {$_.Name -NotLike '\\*'} | select Name | Sort-Object -Property Name | Select-Object -Last 1

Or, if the drive letter is known to be in the range A to Z, then it would be more sensible to use -Like '[A-Z]*' instead of -NotLike '\\*'.

Try something like this

Get-WMIObject Win32_Volume | where {$_.Name -eq "E:\"}

this should give you a list of objects wich you can access like an array. Also there is a lot of useful information here https://technet.microsoft.com/en-gb/library/2007.04.powershell.aspx
