VBA- filter unecessary folders - vba

Question

I have a question about reading files within folders. I found this code:
sub sample()
Dim FileSystem As Object
Dim HostFolder As String
HostFolder = "C:\"
Set FileSystem = CreateObject("Scripting.FileSystemObject")
DoFolder FileSystem.GetFolder(HostFolder)
end sub
Sub DoFolder(Folder)
Dim SubFolder
For Each SubFolder In Folder.SubFolders
DoFolder SubFolder
Next
Dim File
For Each File In Folder.Files
' Operate on each file
Next
End Sub
But how would you go about avoiding a specific folder which is within the original one?
Let's say the you have a folder A which in turn has several folder Bs. within these folders, there are the file required but also another folder, always with the same name, let's say C.
How would you filter out folders Cs?
Thank you for your time

You can try something like this:
' List of complete path of files in folder / subfolders
' Needs to add "Microsoft Scripting Runtime" reference to your file
Sub FolderFilesPath(ByVal pFolder As String, ByRef pColFiles As Collection, _
Optional ByVal pGetSubFolders As Boolean, Optional ByVal pFilter As Collection)
Dim sFolder As String
Dim oFSO As New FileSystemObject
Dim oFolder, oSubFolder As Folder
Dim oFile As File
sFolder = IIf(Right(pFolder, 1) <> "\", pFolder & "\", pFolder)
Set oFolder = oFSO.GetFolder(sFolder)
If Not ExistsInCollection(pFilter, sFolder) Then
For Each oFile In oFolder.Files
pColFiles.Add oFile
Next oFile
If pGetSubFolders Then
For Each oSubFolder In oFolder.SubFolders
FolderFilesPath oSubFolder.Path, pColFiles, pGetSubFolders, pFilter
Next
End If
End If
End Sub
' Vba collection contains
Function ExistsInCollection(col As Collection, key As Variant) As Boolean
On Error GoTo err
ExistsInCollection = True
IsObject (col.Item(key))
Exit Function
err:
ExistsInCollection = False
End Function
'------------------------------------------------------------------------------
Sub TestMe()
Dim colFiles As New Collection, sFilePath As Variant
Dim colExcludedFolders As New Collection
Dim sHostFolder As String
sHostFolder = "C:\temp"
With colExcludedFolders
' add folders you want to exclude
.Add sHostFolder & "\C\", sHostFolder & "\C\"
End With
FolderFilesPath ThisWorkbook.Path, colFiles, True, colExcludedFolders
' colFiles contains filtered files
For Each sFilePath In colFiles
With sFilePath
' do what you want with filtered files
Debug.Print .Path & " - " & .Name & " - " & .DateCreated
End With
Next sFilePath
End Sub
