More efficient way to write command prompts in VBA? - vba

Question

My macro for Word highlights specific words from a specified list for each document in a folder. At the end of the macro, I would like to append the names of each of these files to include "_Highlight" using the command line. I am not too familiar with using the Command Prompt in VBA, so my code ended up being messy.
I am trying to replicate the following command prompt in VBA.
for %a in (“C:\path\*.docx*”) do ren “%~a” “%~Na_Highlight%~Xa”
For the actual file path, I select a folder in FileDialog and store it in a variable to be used in the command prompt, strShellFldr. I am having some trouble concatenating all pieces of the code, especially with special characters, spaces, and quotation literals.
Here is what I tried:
The code below runs just fine, however it seems quite cumbersome. Is there a more efficient way to write this?
Shell.Run "cmd.exe /c" & "for %a in" & Chr(32) & "(" & Chr(34) & strShellFldr & Chr(34) & ")" & Chr(32) & "do ren" & Chr(32) & Chr(34) & "%~a" & Chr(34) & Chr(32) & Chr(34) & "%~Na_Hilight%~Xa" & Chr(34)
Is there a native VBA function that allows you to append a file name maybe?
Thank you for your help and my apologies for posting some wretched code on here.

Answer 1

This piece of VBA code can loop through a list of files in a given folder as input, and add "_Highlight" at the end of the name, just before the file extension:
example:
MyFile.txt --> MyFile_Hightlight.txt
Public Sub RenameFiles(Folder As String)
Dim oFSO As Scripting.FileSystemObject
Dim oFolder As Scripting.Folder
Dim oFile As Scripting.File
Dim ext As String
Dim Name As String
On Error GoTo ERROR_TRAP
Set oFSO = New Scripting.FileSystemObject
Set oFolder = oFSO.GetFolder(Folder)
For Each oFile In oFolder.Files
ext = Split(oFile.Name, ".")(UBound(Split(oFile.Name, ".")))
Name = Left$(oFile.Path, Len(oFile.Path) - Len(ext) - 1)
oFSO.MoveFile Name & "." & ext, Name & "_Highlight" & "." & ext
Next oFile
Set oFSO = Nothing
Set oFolder = Nothing
Set oFile = Nothing
Exit Sub
ERROR_TRAP:
Debug.Print "ERROR : RenameFiles (" & oFolder.Name & ")"
End Sub
Do not forget to add Microsoft Scripting Runtime reference first in your VB Editor.
