Loop through all Folders and SubFolders

Good evening,

How can I change the following code to select a folder and look for all *.data files within that folder and subfolders?

Thank you!

Sub DoIt()
    Dim fld As FileDialog
    Dim sFolderLoc As String
    Dim iCurrentRow As Long
    Dim i As Long
    Dim sTxtFilename As String

    Dim j As Long
    Dim sLine As String

    Dim sComputedMaximum
    Dim sComputedMinimum

    With ThisWorkbook.ActiveSheet
        .Range("A1") = "File Name"
        .Range("B1") = "Computed Results"
        .Range("C1") = "Blank"
        .Range("D1") = "Computed Maximum"
        .Range("E1") = "Computed Minimum"
    End With

    iCurrentRow = 1
    
    'sFolderLoc = ThisWorkbook.ActiveSheet.Cells(2, 9).Value
    'Set fld = Application.FileDialog(msoFileDialogFolderPicker)
        'open file picker instead of a folder picker
    Set fld = Application.FileDialog(msoFileDialogFilePicker)
    
        'set file picker dialog preferences
    With fld
        .Title = "Pick your file type"
        .AllowMultiSelect = False
            'you may want to comment out the next two lines if you want to allow users to select a variety of file types
        .Filters.Clear
        .Filters.Add "Text Files", "*.data"
        If .Show <> -1 Then GoTo Exit_DoIt
        sFolderLoc = fld.SelectedItems(1)
    End With
    
    'sTxtFilename = ThisWorkbook.ActiveSheet.Cells(2, 10).Value
        'set file type based upon what the user has selected
    sTxtFilename = "*." & Right(sFolderLoc, Len(sFolderLoc) - InStrRev(sFolderLoc, "."))
    sComputedResults = "Computed Results: "
    sComputedMaximum = "Computed Maximum: "
    sComputedMinimum = "Computed Minimum: "

        'set folder based upon location of file user has selected
    sFolderLoc = Left(sFolderLoc, InStrRev(sFolderLoc, "\"))

    ' this assumes all files of type data are your data
    sTxtFilename = Dir(sFolderLoc & "\" & sTxtFilename)

    Do While sTxtFilename <> ""

        iCurrentRow = iCurrentRow + 1

        Open sFolderLoc & "\" & sTxtFilename For Input As #1

        ' no error checking here, assumes all txt files are ok
        Do While Not EOF(1)

            Input #1, sLine

            If Left(sLine, Len(sComputedResults)) = sComputedResults Then
                sLine = Right(sLine, Len(sLine) - Len(sComputedResults))

                ThisWorkbook.ActiveSheet.Range("B" & iCurrentRow) = sLine
            ElseIf Left(sLine, Len(sComputedMaximum)) = sComputedMaximum Then
                sLine = Right(sLine, Len(sLine) - Len(sComputedMaximum))

                ThisWorkbook.ActiveSheet.Range("D" & iCurrentRow) = sLine
            ElseIf Left(sLine, Len(sComputedMinimum)) = sComputedMinimum Then

            End If
        Loop
        ThisWorkbook.ActiveSheet.Range("A" & iCurrentRow) = sTxtFilename
        Close #1
        'find next txt file
        sTxtFilename = Dir
    Loop
    
Exit_DoIt:
    Set fld = Nothing
    
End Sub

Hi crepe,

try this update, with a subfolder function:
