Assign next available drive letter from command line other than diskpa

Hello @ricardobohner,

I do NOT have the exact answer that you are looking for, but, to find ALL available drives letters that are NOT in use, you could use this:

Code:

PowerShell $Available_Drives='ABCDEFGHIJKLMNOPQRSTUVWXYZ' -Split '' ^| Where-Object {$_ -NotIn ([System.IO.DriveInfo]::GetDrives().Name).Substring(0,1)}; Write-Host $Available_Drives

The above also excludes the DVD drive letter if you have one !

To find the next available drive letter is NOT straight forward as it would rely on if your current drive has missing drive letters in the structure. For example: C: D: H: M: N: Q: etc.

I hope this helps.

EDIT:

I have just found this for you > Getting a Free Drive Letter

There is one there that might interest you as you can also change Select-Object -First 1 to Select-Object -Last 1:

Code:

$DriveList = Get-PSDrive -PSProvider filesystem | foreach({($_.Root).Replace(":\","")})
$AllDrives = [char[]]([int][char]'E'..[int][char]'Z')
$NextDriveLetter = ($AllDrives | Where-Object { $DriveList -notcontains $_ } | Select-Object -First 1) + ":"
Write-Host $DriveList `n; Write-Host $AllDrives `n; Write-Host $NextDriveLetter

Thank you paul

You are VERY welcome.

Hello @SIW2,

I ran the Script and it came back with drive letter E:, which is my DVD drive letter.
