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.
- Count all files in a folder and subfolder
- Count all files of a specific type in a folder and subfolders
- 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.
- None known.
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
- 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.
