Excel VBA批量修改文件夹下的文件名

今天，有同事提出想批量修改文件名，规则比较简单，在第五位后加“-”即可，

上网没找到相关工具，就自己做了个excel，用宏代码修改。

代码如下：

Private Sub CommandButton1_Click()

Dim varFileList As Variant

MsgBox "选择要重命名文件所在的文件夹,点击确定！"

With Application.FileDialog(msoFileDialogFolderPicker)
    .AllowMultiSelect = False
    .Show
   
    If .SelectedItems.Count = 0 Then Exit Sub '未选择文件夹
   
    renamepath = .SelectedItems(1)
   
    If Right(renamepath, 1) <> "\" Then
        renamepath = renamepath + "\"
    End If
End With

'获取文件夹中的所有文件列表
varFileList = fcnGetFileList(renamepath)

If Not IsArray(varFileList) Then
    MsgBox "未找到文件", vbInformation
    Exit Sub
End If

For l = 0 To UBound(varFileList)
    Dim fs
    Set fs = CreateObject("Scripting.FileSystemObject")
    oName = renamepath & CStr(varFileList(l))
    If fs.FileExists(oName) And Len(CStr(varFileList(l))) > 5 Then
        nName = renamepath & Left(CStr(varFileList(l)), 5) & "-" & Mid(CStr(varFileList(l)), 6)
        Name oName As nName
    End If
Next l

MsgBox "全部修改成功！哈哈", vbInformation

End Sub

Private Function fcnGetFileList(ByVal strPath As String, Optional strFilter As String) As Variant
' 将文件列表放到数组
Dim f As String
Dim i As Integer
Dim FileList() As String

If strFilter = "" Then strFilter = "*.*"
    Select Case Right(strPath, 1)
    Case "\", "/"
    strPath = Left(strPath, Len(strPath) - 1)
End Select

ReDim Preserve FileList(0)
f = Dir(strPath & "\" & strFilter)
Do While Len(f) > 0
    ReDim Preserve FileList(i) As String
    FileList(i) = f
    i = i + 1
    f = Dir()
Loop
If FileList(0) <> Empty Then
    fcnGetFileList = FileList
Else
    fcnGetFileList = False
End If

End Function
