I have tried to write VBA code to extract the 10 most used folders in Windows except Outlook folders, sub-folders and program folders

However, I get compile error : for each control variable must be variant or object and the code below is highlighted


Code: 
 For Each folderPath In GetFoldersOnDrive("C:\", False)
It would be appreciated if someone could amend my code



See full code below



Code: 
 Sub MostUsedFolders()
    
    Dim dict As Object
    Dim arr() As Variant
    Dim i As Long
    Dim rng As Range
    Dim folderPath As String
    Dim folder As Object
    
    'Create a dictionary to hold the folder paths and their usage count
    Set dict = CreateObject("Scripting.Dictionary")
    
    'Loop through each folder on the C:\ drive
    For Each folderPath In GetFoldersOnDrive("C:\", False)
        Set folder = CreateObject("Scripting.FileSystemObject").GetFolder(folderPath)
        If Not IsOutlookFolder(folder) And Not IsProgramFolder(folder) Then
            CountItems folder, dict
        End If
    Next folderPath
    
    'Put the folder paths and their usage count into an array
    ReDim arr(1 To dict.Count, 1 To 2)
    i = 1
    For Each folderPath In dict
        arr(i, 1) = folderPath
        arr(i, 2) = dict(folderPath)
        i = i + 1
    Next folderPath
    
    'Sort the array by the usage count in descending order
    SortArray arr
    
    'Clear column A
    Set rng = Range("A1", Range("A1").End(xlDown))
    rng.ClearContents
    
    'Paste the folder paths into column A
    Set rng = Range("A1").Resize(UBound(arr, 1), 1)
    rng.Value = arr
    
End Sub

Function GetFoldersOnDrive(drivePath As String, includeSubfolders As Boolean) As Collection
    
    Dim fso As Object
    Dim folder As Object
    Dim subFolder As Object
    Dim folders As New Collection
    
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set folder = fso.GetFolder(drivePath)
    
    For Each subFolder In folder.subFolders
        If includeSubfolders Then
            folders.Add subFolder.Path
        Else
            folders.Add subFolder.Path, subFolder.Path
        End If

    For Each item In folder.Files
        'If the item is a file, add its parent folder path to the dictionary
        key = folder.Path
        If dict.Exists(key) Then
            dict(key) = dict(key) + 1
        Else
            dict.Add key, 1
        End If
    Next item
    
End Function

    IsOutlookFolder = folderName = "Outlook" Or folderName = "Outlook Files" Or folderName = "Local Settings" Or folderName = "Roaming" Or folderName = "AppData" Or folderName = "Microsoft" Or folderName = "Office"
End Function

Function IsProgramFolder(folder As Object) As Boolean
    Dim folderName As String
    folderName = folder.Name
    IsProgramFolder = folderName = "Program Files" Or folderName = "Program Files (x86)" Or folderName = "Windows"
End Function

Sub SortArray(arr() As Variant)

Dim i As Long
Dim j As Long
Dim temp As Variant

For i = LBound(arr, 1) To UBound(arr, 1) - 1
    For j = i + 1 To UBound(arr, 1)
        If arr(j, 2) > arr(i, 2) Then
            temp = arr(j, 1)
            arr(j, 1) = arr(i, 1)
            arr(i, 1) = temp
            temp = arr(j, 2)
            arr(j, 2) = arr(i, 2)
            arr(i, 2) = temp
        End If
    Next j
Next i

End Sub

If GetFoldersOnDrive (which appears to be a custom function that you are not showing) returns an object, you cannot set the return value of the function to a string variable. That's what your error description suggests to me.

I have managed to get this to work now, but only need the 10 most used folders to be copied in Col A. It would be appreciatted if someone could kindly amend my code

Code: 
 Function GetFoldersOnDrive(drivePath As String, includeSubfolders As Boolean) As Collection
    
    Dim FSO As Object
    Dim folder As Object
    Dim subFolder As Object
    Dim folders As New Collection
    
    Set FSO = CreateObject("Scripting.FileSystemObject")
    Set folder = FSO.GetFolder(drivePath)
    
    For Each subFolder In folder.subFolders
        If includeSubfolders Then
            folders.Add subFolder.Path
        Else
            folders.Add subFolder.Path, subFolder.Path
        End If
    Next subFolder
    
    Set GetFoldersOnDrive = folders
    
End Function

Function CountItems(folder As Object, dict As Object)
    
    Dim item As Object
    Dim key As String
    
    'Loop through each item in the folder
    On Error Resume Next ' Ignore any errors that occur while accessing files and folders
    For Each item In folder.Files
        'If the item is a file, add its parent folder path to the dictionary
        key = folder.Path
        If dict.Exists(key) Then
            dict(key) = dict(key) + 1
        Else
            dict.Add key, 1
