Question

Public fso As Scripting.FileSystemObject
Set fso = New Scripting.FileSystemObject
fso.CreateFolder ("C:\Users\<my_username>\DataEntry\logs")

我正在尝试创建嵌套目录。在这种情况下，DataEntry目录将不存在，所以基本上我想在DataEntry\logs下创建2个目录C:\Users\<username>

如果我输入命令提示符，我可以使用mkdir创建该目录而不会出现任何问题。但是，我根本无法让VBA创建该文件夹而且我得到了：

Run-time error '76':

Path not found

我正在使用Excel VBA 2007/2010

需要一次创建一个文件夹。您可以使用这样的代码来执行此操作：

Sub tgr()

    Dim strFolderPath As String
    Dim strBuildPath As String
    Dim varFolder As Variant

    strFolderPath = "C:\Users\<my_username>\DataEntry\logs"

    If Right(strFolderPath, 1) = "\" Then strFolderPath = Left(strFolderPath, Len(strFolderPath) - 1)
    For Each varFolder In Split(strFolderPath, "\")
        If Len(strBuildPath) = 0 Then
            strBuildPath = varFolder & "\"
        Else
            strBuildPath = strBuildPath & varFolder & "\"
        End If
        If Len(Dir(strBuildPath, vbDirectory)) = 0 Then MkDir strBuildPath
    Next varFolder

    'The full folder path has been created regardless of nested subdirectories
    'Continue with your code here

End Sub

tigeravatar的循环答案可能有效，但它有点难以阅读。 FileSystemObject不是自己对字符串处理进行微管理，而是具有可用的路径操作函数，并且递归比循环更容易阅读。

这是我使用的功能：

Function CreateFolderRecursive(path As String) As Boolean
    Dim FSO As New FileSystemObject

    'If the path exists as a file, the function fails.
    If FSO.FileExists(path) Then
        CreateFolderRecursive = False
        Exit Function
    End If

    'If the path already exists as a folder, don't do anything and return success.
    If FSO.FolderExists(path) Then
        CreateFolderRecursive = True
        Exit Function
    End If

    'recursively create the parent folder, then if successful create the top folder.
    If CreateFolderRecursive(FSO.GetParentFolderName(path)) Then
        If FSO.CreateFolder(path) Is Nothing Then
            CreateFolderRecursive = False
        Else
            CreateFolderRecursive = True
        End If
    Else
        CreateFolderRecursive = False
    End If
End Function

同意 MarkD 使用递归的建议，这是我来这里寻找的代码。在提供的路径使用不存在的根文件夹的情况下，它将导致无限循环。添加到 MarkD 的解决方案以检查零长度路径。

Function CreateFolderRecursive(path As String) As Boolean
    Static FSO As FileSystemObject
 
    'Initialize FSO variable if not already setup
    If FSO Is Nothing Then Set lFSO = New FileSystemObject

    'Is the path paramater populated
    If Len(path) = 0 Then
      CreateFolderRecursive = False
      Exit Function
    End If

    'If the path exists as a file, the function fails.
    If FSO.FileExists(path) Then
        CreateFolderRecursive = False
        Exit Function
    End If
 
    'If the path already exists as a folder, don't do anything and return success.
    If FSO.FolderExists(path) Then
        CreateFolderRecursive = True
        Exit Function
    End If
 
    'recursively create the parent folder, then if successful create the top folder.
    If CreateFolderRecursive(FSO.GetParentFolderName(path)) Then
        If FSO.CreateFolder(path) Is Nothing Then
            CreateFolderRecursive = False
        Else
           CreateFolderRecursive = True
        End If
    Else
        CreateFolderRecursive = False
    End If
End Function

FileSystemObject.CreateFolder用于创建目录和子目录
