Need to modify my VBA code to include subfolders as well - vba

Question

I have created a VBA code that loops through all excel workbooks in a given folder , opens then, refreshes the sheet, pauses for 10 seconds, closes and saves and moves on to the next. The issue I am facing is that it wont do it for the excel workbooks in the subfolder, Please can someone assist.
The code is as per below:
Sub LoopAllExcelFilesInFolder()
'PURPOSE: To loop through all Excel files in a user specified folder and perform a set task on them
'SOURCE: www.TheSpreadsheetGuru.com
Dim wb As Workbook
Dim myPath As String
Dim myFile As String
Dim myExtension As String
Dim FldrPicker As FileDialog
'Optimize Macro Speed
Application.ScreenUpdating = False
Application.EnableEvents = False
Application.Calculation = xlCalculationManual
'Retrieve Target Folder Path From User
Set FldrPicker = Application.FileDialog(msoFileDialogFolderPicker)
With FldrPicker
.Title = "Select A Target Folder"
.AllowMultiSelect = False
If .Show <> -1 Then GoTo NextCode
myPath = .SelectedItems(1) & "\"
End With
'In Case of Cancel
NextCode:
myPath = myPath
If myPath = "" Then GoTo ResetSettings
'Target File Extension (must include wildcard "*")
myExtension = "*.xls*"
'Target Path with Ending Extention
myFile = Dir(myPath & myExtension)
'Loop through each Excel file in folder
Do While myFile <> ""
'Set variable equal to opened workbook
Set wb = Workbooks.Open(Filename:=myPath & myFile)
'Ensure Workbook has opened before moving on to next line of code
DoEvents
'Change First Worksheet's Background Fill Blue
Application.Calculate
ActiveWorkbook.RefreshAll
Application.Wait (Now + TimeValue("0:00:10"))
'Save and Close Workbook
wb.Close SaveChanges:=True
'Ensure Workbook has closed before moving on to next line of code
DoEvents
'Get next file name
myFile = Dir
Loop
'Message Box when tasks are completed
MsgBox "Task Complete!"
ResetSettings:
'Reset Macro Optimization Settings
Application.EnableEvents = True
Application.Calculation = xlCalculationAutomatic
Application.ScreenUpdating = True
End Sub

Its probably an old question indeed, but still, I enjoyed writing it somehow. And in my solution, you get some nice printing in the console. Here you go:
Option Explicit
Function GetFiles(ByVal Folder As String) As Collection
Dim strFile As String
Set GetFiles = New Collection
strFile = Dir(Folder & "\*")
Do While strFile <> ""
GetFiles.Add strFile
strFile = Dir
Loop
End Function
Function GetFolders(ByVal Folder As String) As Collection
Dim strFile As String
Set GetFolders = New Collection
strFile = Dir(Folder & "\*", vbDirectory)
Do While strFile <> ""
If GetAttr(Folder & "\" & strFile) And vbDirectory Then GetFolders.Add strFile
strFile = Dir
Loop
End Function
Sub LoopThroughSubfoldersAsWell()
Dim colFoFi As Collection
Dim varEl01 As Variant
Dim varEl02 As Variant
Dim varEl03 As Variant
Dim strLine As String: strLine = "--------------------------"
Dim strAddress As String: strAddress = "C:\Users\UserName\Desktop\Testing01\"
Debug.Print strAddress
Set colFoFi = GetFiles(strAddress)
For Each varEl01 In colFoFi
Debug.Print varEl01
Next varEl01
Debug.Print strLine
Set colFoFi = GetFolders(strAddress)
For Each varEl01 In colFoFi
If Len(varEl01) > 2 Then 'to avoid some hidden stuff
Set varEl02 = GetFiles(strAddress & varEl01)
Debug.Print (strAddress & varEl01)
For Each varEl03 In varEl02
Debug.Print varEl03
Next varEl03
Debug.Print strLine
End If
Next varEl01
End Sub
