Hello

I am trying to look for this thing but hard time finding this - using FSO -
1. open a main folder and then
2. go through each sub folder under that main folder and if you see any files, simply delete it

How can i do that in VBA?

Thank You
Rayne

The following code will let the user pick any file in a folder. It will then delete any file within that folder plus any subfolders. The empty subfolders will not be deleted.
Dim FSO As Object

Sub SnarkHunt()
Dim TopFolderName As String
Dim TopFolderObj As Object
        'Input Path and Search Term
TopFolderName = Application.GetOpenFilename("Files (*.*), *.*", _
        Title:="Pick any file in desired folder, then click Open. EE Q28312844")
If TopFolderName = "False" Then Exit Sub
TopFolderName = Left(TopFolderName, InStrRev(TopFolderName, Application.PathSeparator) - 1)

Application.ScreenUpdating = False
Set FSO = CreateObject("Scripting.FileSystemObject")
Set TopFolderObj = FSO.GetFolder(TopFolderName)

SubFolderRecursion TopFolderObj
Set FSO = Nothing
MsgBox "Done"
End Sub

Sub SubFolderRecursion(OfFolder As Object)

Dim SubFolder As Object
SearchFolder OfFolder.Path
For Each SubFolder In OfFolder.SubFolders
    SubFolderRecursion SubFolder
    SearchFolder SubFolder.Path
Next SubFolder
End Sub
    
Sub SearchFolder(strPath As String)
Dim fld As Object
Dim sfl As Object
Dim strFile As String
Dim strFirstAddress As String

On Error Resume Next

strFile = Dir(strPath & "\*.xls*")
Do While strFile <> ""
    If strFile <> ActiveWorkbook.Name Then
        Kill strPath & "\" & strFile
    End If
    strFile = Dir
Loop

On Error GoTo 0
End Sub

I revised the code so it would delete the subfolders as well as the files. I also added the ability to specify a file naming pattern, i.e. delete only files like *.xl*, *.pdf or *.*
Dim FSO As Object

Sub RecursiveFileDeletion()
'Deletes files of a specified name pattern within a user-specified folder and its subfolders. Uses recursion.
Dim sNamePattern As String, TopFolderName As String
Dim TopFolderObj As Object
sNamePattern = "*.*"        'Delete just Excel files *.xl*, delete all files *.*

TopFolderName = Application.GetOpenFilename("Files (" & sNamePattern & "), " & sNamePattern, _
        Title:="Pick any file in desired folder, then click Open, EE Q28312844")
If TopFolderName = "False" Then Exit Sub
TopFolderName = Left(TopFolderName, InStrRev(TopFolderName, Application.PathSeparator) - 1)

Application.ScreenUpdating = False
Set FSO = CreateObject("Scripting.FileSystemObject")
Set TopFolderObj = FSO.GetFolder(TopFolderName)

SubFolderRecursion TopFolderObj, sNamePattern
Set FSO = Nothing
MsgBox "Done"
End Sub

Sub SubFolderRecursion(OfFolder As Object, sNamePattern As String)
Dim SubFolder As Object
SearchFolder OfFolder.Path, sNamePattern
For Each SubFolder In OfFolder.SubFolders
    SubFolderRecursion SubFolder, sNamePattern
    SearchFolder SubFolder.Path, sNamePattern
    On Error Resume Next
    If Dir(SubFolder.Path & "\*.*") = "" Then RmDir SubFolder.Path      'Delete the subfolder if it is empty
    On Error GoTo 0
Next SubFolder
End Sub
    
Sub SearchFolder(strPath As String, sNamePattern As String)
Dim strFile As String
strFile = Dir(strPath & "\" & sNamePattern)
On Error Resume Next
Do While strFile <> ""
    If strFile <> ActiveWorkbook.Name Then Kill strPath & "\" & strFile
    strFile = Dir
Loop
On Error GoTo 0
End Sub

Apologize for not getting your name right in the first place :(
I sometimes mistake one expert from other based of their usernames.

Thank you Brad - that is awesome - 5 stars for the file type thing :) as I knew there would be multiple file types situation possible in my case.
