Introduction:
This macro can be used to count how many files exist in a folder and subfolders. In addition, if passed the file extension, it can also be used to count only files of a specific type. (For example "xls" files.) If you are looking for a macro that counts files within a specific folder only (ignoring subfolders), please see this entry.
Macro Purpose:
- Count all files in a folder and subfolder
- Count all files of a specific type in a folder and subfolders
Examples of where this function shines:
- When checking if you should process a folder for any reason, this can be used to quickly test if any files worth looking at exist inside.
Macro Weakness(es):
- None known.
Versions Tested:
This function has been tested with Excel 2007. Due to the use of the InStrRev function, it will not work in Excel 97. While I have not tested it with Excel 2000 and Excel 2002 (XP) without any modifications, I don't expect any issues with it. (If you find one, please leave a comment at the bottom of the article.)
VBA Code Required:
- Place the following code in a standard module of the workbook you wish to use it in.
Private Function CountFiles_FolderAndSubFolders(strFolder As String, Optional strExt As String = "*.*") As Double
'Author : Ken Puls (www.excelguru.ca)
'Function purpose: To count files in a folder and all subfolders. If a file extension is provided,
' then count only files of that type, otherwise return a count of all files.
Dim objFso As Object
Dim objFiles As Object
Dim objSubFolder As Object
Dim objSubFolders As Object
Dim objFile As Object
'Set Error Handling
On Error GoTo EarlyExit
'Create objects to get a count of files in the directory
Set objFso = CreateObject("Scripting.FileSystemObject")
Set objFiles = objFso.getfolder(strFolder).Files
Set objSubFolders = objFso.getfolder(strFolder).subFolders
'Count files (that match the extension if provided)
If strExt = "*.*" Then
CountFiles_FolderAndSubFolders = objFiles.Count
Else
For Each objFile In objFiles
If UCase(Right(objFile.Path, (Len(objFile.Path) - InStrRev(objFile.Path, ".")))) = UCase(strExt) Then
CountFiles_FolderAndSubFolders = CountFiles_FolderAndSubFolders + 1
End If
Next objFile
End If
'Request count of files in subfolders
For Each objSubFolder In objSubFolders
CountFiles_FolderAndSubFolders = CountFiles_FolderAndSubFolders + _
CountFiles_FolderAndSubFolders(objSubFolder.Path, strExt)
Next objSubFolder
EarlyExit:
'Clean up
On Error Resume Next
Set objFile = Nothing
Set objFiles = Nothing
Set objFso = Nothing
On Error GoTo 0
End Function
How to use the code:
- Call it from another routine, as shown using a FileDialog example below. (FileDialogFolderPicker may not work in Excel 2000.)
- Please note that you should provide the full file path to the folder as the argument.
- You may supply or ignore the trailing on a directory if you choose. It will work either way.
Sub Test()
'Author : Ken Puls (www.excelguru.ca)
'Macro Purpose: Test the CountFiles function
Dim flDlg As FileDialog
Dim dblCount As Double
Set flDlg = Application.FileDialog(msoFileDialogFolderPicker)
flDlg.Show
dblCount = CountFiles_FolderAndSubFolders(flDlg.SelectedItems(1))
Debug.Print dblCount
End Sub
