Vba 复制文件夹和所有子文件夹，而不覆盖现有文件夹

0

我正在尝试使用fso.folder copy在网络驱动器上创建备份数据库。我的目的是移动文件夹中的所有文件和子文件夹，但如果备份驱动器上已存在文件，请跳过该文件，然后复制文件夹中的其余文件

FSO.copyfolder Source:=Sourcefilename, Destination:=Destinfilename, OverwriteFiles:= False

---

但是，脚本在找到现有文件时会出错。任何建议都将不胜感激。

请尝试下一个代码：

Sub testCopyFolder()
 Dim FSO As Object, SourceFold As String, DestinationFold As String
 
 SourceFold = "Source folder path"           ' ending in "\"
 DestinationFold = "Destination folder path" ' ending in "\"
 Set FSO = CreateObject("Scripting.FileSystemObject")
 
 If Not FSO.FolderExists(DestinationFold) Then
    FSO.CopyFolder SourceFold, DestinationFold
 End If
End Sub

---

您可以以类似的方式继续复制文件。当然，请使用

FSO.FileExists（）

Sub testCopyFolder()
 Dim FSO As Object, SourceFold As String, DestinationFold As String
 
 SourceFold = "Source folder path"           ' ending in "\"
 DestinationFold = "Destination folder path" ' ending in "\"
 Set FSO = CreateObject("Scripting.FileSystemObject")
 
 If Not FSO.FolderExists(DestinationFold) Then
    FSO.CopyFolder SourceFold, DestinationFold
 End If
End Sub

您可以以类似的方式继续复制文件。当然，使用
FSO.FileExists（）
…
