You can get fancy changing A-F etc to ASCII codes but basically, it is something like this
Dim lines() As String = IO.File.ReadAllLines("words.txt")
For Each line As String In lines
    If line.StartsWith("A") Or line.StartsWith("B") Or line.StartsWith("C") Or line.StartsWith("D") Or line.StartsWith("E") Or line.StartsWith("F") Then
        'Add to the first list box
    Else If ...
        ....
    End If
Next

Open in new window

Also, check for blank lines, file do not exist, file is locked etc.

In ASCII A is 65 and 70 so you could have a condition
If Asc(line.Substring(1)) >= 65 And Asc(line.Substring(1)) <= 70 Then

Open in new window
