循环访问用户指定的根目录中的子文件夹和文件

Question

我的循环脚本通过单个文件工作正常,但我现在需要它也查看/为多个目录.我被困了....

事情需要发生的事情:

• 提示用户选择所需内容的根目录
• 我需要脚本来查找该根目录中的任何文件夹
• 如果脚本找到一个,它会打开第一个(所有文件夹,因此文件夹没有特定的搜索过滤器)
• 打开后,我的脚本将遍历文件夹中的所有文件并执行它需要执行的操作
• 它完成后关闭文件,关闭目录并移动到下一个,等等.
• 循环直到所有文件夹都被打开/扫描

这就是我所拥有的,这是行不通的,我知道是错的:

MsgBox "Please choose the folder."
Application.DisplayAlerts = False
With Application.FileDialog(msoFileDialogFolderPicker)
    .InitialFileName = "\\blah\test\"
    .AllowMultiSelect = False
    If .Show <> -1 Then MsgBox "No folder selected! Exiting script.": Exit Sub
    CSRootDir = .SelectedItems(1)
End With
folderPath = Dir(CSRootDir, "\*")

Do While Len(folderPath) > 0
    Debug.Print folderPath
    fileName = Dir(folderPath & "*.xls")
    If folderPath <> "False" Then
        Do While fileName <> ""
            Application.ScreenUpdating = False
            Set wbkCS = Workbooks.Open(folderPath & fileName)

            --file loop scripts here

        Loop  'back to the Do
Loop    'back to the Do

最终守则.它循环遍历每个子目录中的所有子目录和文件.

Dim FSO As Object, fld As Object, Fil As Object
Dim fsoFile As Object 
Dim fsoFol As Object 
Dim fileName As String

    MsgBox "Please choose the folder."
    Application.DisplayAlerts = False
    With Application.FileDialog(msoFileDialogFolderPicker)
         .InitialFileName = "\\blah\test\"
         .AllowMultiSelect = False
         If .Show <> -1 Then MsgBox "No folder selected! Exiting script.": Exit Sub
         folderPath = .SelectedItems(1)
    End With

    If Right(folderPath, 1) <> "\" Then folderPath = folderPath + "\"
         Set FSO = CreateObject("Scripting.FileSystemObject")
         Set fld = FSO.getfolder(folderPath)
    If FSO.folderExists(fld) Then
         For Each fsoFol In FSO.getfolder(folderPath).subfolders
              For Each fsoFile In fsoFol.Files
                   If Mid(fsoFile.Name, InStrRev(fsoFile.Name, ".") + 1) = "xls" Then
    fileName = fsoFile.Name
    Application.ScreenUpdating = False
    Set wbkCS = Workbooks.Open(fsoFile.Path)

    'My file handling code


                End If
              Next
         Next
    End If

您可能会发现它更容易使用FileSystemObject,财产以后这样

这会将文件夹/文件列表转储到 Immediate window

Option Explicit

Sub Demo()
    Dim fso As Object 'FileSystemObject
    Dim fldStart As Object 'Folder
    Dim fld As Object 'Folder
    Dim fl As Object 'File
    Dim Mask As String

    Set fso = CreateObject("scripting.FileSystemObject") ' late binding
    'Set fso = New FileSystemObject 'or use early binding (also replace Object types)

    Set fldStart = fso.GetFolder("C:\Your\Start\Folder") ' <-- use your FileDialog code here

    Mask = "*.xls"
    Debug.Print fldStart.Path & "\"
    ListFiles fldStart, Mask
    For Each fld In fldStart.SubFolders
        ListFiles fld, Mask
        ListFolders fld, Mask
    Next
End Sub


Sub ListFolders(fldStart As Object, Mask As String)
    Dim fld As Object 'Folder
    For Each fld In fldStart.SubFolders
        Debug.Print fld.Path & "\"
        ListFiles fld, Mask
        ListFolders fld, Mask
    Next

End Sub

Sub ListFiles(fld As Object, Mask As String)
    Dim fl As Object 'File
    For Each fl In fld.Files
        If fl.Name Like Mask Then
            Debug.Print fld.Path & "\" & fl.Name
        End If
    Next
End Sub

这是一个VBA解决方案,不使用外部对象.

由于Dir()函数的局限性,您需要一次获取每个文件夹的全部内容,而不是使用递归算法进行爬网.

Function GetFilesIn(Folder As String) As Collection
  Dim F As String
  Set GetFilesIn = New Collection
  F = Dir(Folder & "\*")
  Do While F <> ""
    GetFilesIn.Add F
    F = Dir
  Loop
End Function

Function GetFoldersIn(Folder As String) As Collection
  Dim F As String
  Set GetFoldersIn = New Collection
  F = Dir(Folder & "\*", vbDirectory)
  Do While F <> ""
    If GetAttr(Folder & "\" & F) And vbDirectory Then GetFoldersIn.Add F
    F = Dir
  Loop
End Function

Sub Test()
  Dim C As Collection, F

  Debug.Print
  Debug.Print "Files in C:\"
  Set C = GetFilesIn("C:\")
  For Each F In C
    Debug.Print F
  Next F

  Debug.Print
  Debug.Print "Folders in C:\"
  Set C = GetFoldersIn("C:\")
  For Each F In C
    Debug.Print F
  Next F
End Sub
