采用递归算法删除带有多级子目录的目录
Option Explicit
Private Sub Command1_Click()
Dim strPathName As String
strPathName = ""
strPathName = InputBox("请输入需要删除的文件夹名称∶", "删除文件夹")
If strPathName = "" Then Exit Sub
On Error GoTo ErrorHandle
SetAttr strPathName, vbNormal '此行主要是为了检查文件夹名称的有效性
RecurseTree strPathName
Label1.Caption = "文件夹" & strPathName & "已经删除！"
Exit Sub
ErrorHandle:
MsgBox "无效的文件夹名称:" & strPathName
End Sub
Sub RecurseTree(CurrPath As String)
Dim sFileName As String
Dim newPath As String
Dim sPath As String
Static oldPath As String
sPath = CurrPath & "\"
sFileName = Dir(sPath, 31) '31的含义∶31=vbNormal+vbReadOnly+vbHidden+vbSystem+vbVolume+vbDirectory
Do While sFileName <> ""
If sFileName <> "." And sFileName <> ".." Then
If GetAttr(sPath & sFileName) And vbDirectory Then '如果是目录和文件夹
newPath = sPath & sFileName
RecurseTree newPath
sFileName = Dir(sPath, 31)
Else
SetAttr sPath & sFileName, vbNormal
Kill (sPath & sFileName)
Label1.Caption = sPath & sFileName '显示删除过程
sFileName = Dir
End If
Else
sFileName = Dir
End If
DoEvents
Loop
SetAttr CurrPath, vbNormal
RmDir CurrPath
Label1.Caption = CurrPath
End Sub

如何用程序来Delete Copy Move Rename File/Directory
作者: 王国荣
Private Type SHFILEOPSTRUCT
hwnd As Long
wFunc As Long
pFrom As String
pTo As String
fFlags As Integer
fAnyOperationsAborted As Long
hNameMappings As Long
lpszProgressTitle As String ' only used if FOF_SIMPLEPROGRESS
End Type
'wFunc 的设定值
'FO_COPY Copies the files specified by pFrom to the location specified by pTo.
'FO_DELETE Deletes the files specified by pFrom (pTo is ignored).
'FO_MOVE Moves the files specified by pFrom to the location specified by pTo.
'FO_RENAME Renames the files specified by pFrom.
'fFlag的设定
'FOF_ALLOWUNDO Preserves undo information, if possible.
'FOF_FILESONLY Performs the operation only on files if a wildcard filename
' (*.*) is specified.
'FOF_MULTIDESTFILES Indicates that the pTo member specifies multiple destination
' files (one for each source file) rather than one directory where
' all source files are to be deposited.
'FOF_NOCONFIRMATION Responds with "yes to all" for any dialog box that is displayed.
'FOF_NOCONFIRMMKDIR Does not confirm the creation of a new directory if
' the operation requires one to be created.
'FOF_RENAMEONCOLLISION Gives the file being operated on a new name (such as
' "Copy #1 of...") in a move, copy, or rename operation
' if a file of the target name already exists.
'FOF_SILENT Does not display a progress dialog box.
'FOF_SIMPLEPROGRESS Displays a progress dialog box, but does not show the
' filenames.
'FOF_WANTMAPPINGHANDLE Fills in the hNameMappings member. The handle must be
' freed by using the SHFreeNameMappings function.
