I am looking for a way to programatically determine the drive letters of removeable drives in Windows (specifically USB keys) so that I may find a particular executable and run it.

You can list the drive types for each letter.

I have this on a form.

Option Explicit

Private Sub Command1_Click()
Dim i As Integer
For i = 65 To 90
Debug.Print Chr$(i), DriveType(Chr$(i))
Next i
End Sub

In a module

Option Explicit

Public Declare Function GetDriveType Lib "kernel32" Alias "GetDriveTypeA" (ByVal nDrive As String) As Long

Public Function DriveType(sDrive As String) As String
    Dim sDriveName As String
    Const DRIVE_TYPE_UNDTERMINED = 0
    Const DRIVE_ROOT_NOT_EXIST = 1
    Const DRIVE_REMOVABLE = 2
    Const DRIVE_FIXED = 3
    Const DRIVE_REMOTE = 4
    Const DRIVE_CDROM = 5
    Const DRIVE_RAMDISK = 6
   
    sDriveName = GetDriveType(sDrive & ":\")
    Select Case sDriveName
        Case DRIVE_TYPE_UNDTERMINED
            DriveType = "unknown"
        Case DRIVE_ROOT_NOT_EXIST
            DriveType = "non-existent"
        Case DRIVE_CDROM
            DriveType = "CD-ROM"
        Case DRIVE_FIXED
            DriveType = "local"
        Case DRIVE_RAMDISK
            DriveType = "RAM"
        Case DRIVE_REMOTE
            DriveType = "remote"
        Case DRIVE_REMOVABLE
            DriveType = "removeable"
    End Select
  End Function
