VB Script RefreshAll in folder (with exception)

Question

edited to be more specific:

VBScript below runs through entire folder, opens each *.XLSM file there , refreshes all data connections and saves updated files one by one. Files are also password protected, but it's not that important.

How to enhance the code to AVOID files in folder, based on part or entire filename ? For an example avoid filenames ending with z however with still .xlsm extension.

Expected outcome for files located in the same folder:

abc123.xlsm (refresh); abc123z.xlsm (avoid); file.xlsm (refresh); testz.xlsm (avoid)

Set fso = CreateObject("Scripting.FileSystemObject")
Set xl  = CreateObject("Excel.Application")
xl.Visible = False

For Each f In fso.GetFolder("C:\test\").Files
  If LCase(fso.GetExtensionName(f.Name)) = "xlsm" Then

    Set wb = xl.Workbooks.Open(f.Path ,,,,,"x")

    wb.RefreshAll
    wb.Save
    wb.Close

  End If

Next

xl.Quit

Answer 1

you can try use split command.

file_path =abc123.xlsm
file_name =split(file_path,".")

file_name is an array containing 2 values

file_name (0)=abc123

file_name (1)=xlsm

now you can check if the last char in file_name(0)="Z"

if NOT(right(file_name(0),1)="Z") THEN
    do...
ELSE
    do...
END IF
