Moving files to a folder, Error 13 Type mismatch

Question

I want to move files to created folders. I got a mismatch error every time.

The aim is to create a folder named after the file prefix if it doesn't exist and copy the file to that folder.

I get

mismatch error

Answer 1

Ok. I did solve it in the end—as in it does its job. Instead of to fso.MoveFile I used Name and it worked for my purpose. Still unclear why fso.Movefile didn't work.

The whole code is below if anyone is interested.

Sub loopf()
    Dim AcceptedPrefixes As Object
    Set AcceptedPrefixes = CreateObject("Scripting.Dictionary")
    
    Dim PrefixRange As Range
    Set PrefixRange = ThisWorkbook.Sheets(1).Range("a1:a3")
    
    Dim Cell As Range
    For Each Cell In PrefixRange.Cells
        If Cell <> "" And Not AcceptedPrefixes.exists(Cell.Value) Then
            AcceptedPrefixes.Add CStr(Cell.Value), 0
        End If
    Next

    Dim Directory As String
    Directory = "C:\TEST\"
    
    Dim fsoFSO
    Set fsoFSO = CreateObject("Scripting.FileSystemObject")
    
    Dim filen As Variant
    filen = Dir(Directory)
    While filen <> ""
        Dim FilePrefix As String
        FilePrefix = "" & (Split(filen, "_")(0)) & ""
        
       If Not AcceptedPrefixes.exists(FilePrefix) Then
        Kill Directory & filen
        Else
        If fsoFSO.FolderExists("C:\TEST\" & FilePrefix) Then
        Name "C:\TEST\" & filen As "C:\TEST\" & FilePrefix & "\" & filen
           
      Else: fsoFSO.CreateFolder ("C:\TEST\" & FilePrefix)
      'FSO.MoveFile "C:\TEST\" & filen, "C:\TEST\" & FilePrefix & "\" ---- not working
      Name "C:\TEST\" & filen As "C:\TEST\" & FilePrefix & "\" & filen
      End If
        
        End If
        filen = Dir
    Wend
End Sub

Answer 2

fsoFSO is not fso.

fsoFSO.CreateFolder ...
fso.MoveFile ...

Option Explicit ' Consider this mandatory
' Tools | Options | Editor tab
' Require Variable Declaration
' If desperate declare as Variant
