    Hello

    I'm have a tough time trying to get the drive letter of a usb.

    I am using the ISE in Admin mode

    I have a ps script that resides on a usb drive.  In the script, I'm trying to set the relative path to specific files (relative to the root of the USB it resides on).

    The reason I need to do this is that when I go from work station to work station (as needed), I can simply run the script and have it copy the appropriate files to the appropriate place (from the usb to a specific path on the hd).

    Because on each system, the usb is apt to get a different drive letter, I can't hard code the drive letter in the script.

    Any help would be appreciated.

    Thank you

    Terry

    Hi Terry,

    you can run the following cmd command:

    wmic logicaldisk where drivetype=2 get deviceid

    in PowerShell and then it will look like this:

    cmd /c "wmic logicaldisk where drivetype=2 get deviceid"

    and this will show you the USB drives and their letters...In all cases you have an challenge: how to determine which drive to target if you have more then one USB drive... but this cannot be solved technically

    Hope I could help. Regards,

    It sure can be solved technically.

    Get-PsDrive | Where Description -eq 'My USB label'

    You can also set an event on the USB resource or scan the event log for the latest USB mount.

    Agree, you can do that, but only if you have a uniform naming convention for those :)

    The Drive label may not work for me in some cases.

    I did find a 1 liner by Marco Nuijens that led me to a solution:

    $USBDrive = get-psdrive |where {$_.Root -match ":"} |% {if (Test-Path ($_.Root + "Do Not Delete")){$_.Root}}

    I created a folder called "Do Not Delete" on my thumb drive.  The above looks for it and returns the drive letter.

    So, in my application, Im using it as such:

    $IconPath = -Join ($USBDrive, 'ICON ICO\ICON.txt')
Copy-Item $IconPath "C:\users\default\App Data\Microsoft\Windows\Shell"

    Seems to be working as I need it to.

    Thank You
