Name

RmDir Procedure

Class

Microsoft.VisualBasic.FileSystem

Syntax

RmDir(path)
path (required; String)

The path of the folder to be removed

Description

Removes a folder

Rules at a Glance

  • You may include a drive letter in path; if you don’t specify a drive letter, the folder is assumed to be on the current drive.

  • path can be a fully qualified, relative, or UNC pathname.

  • If the folder contains files or other folders, RmDir will generate runtime error 75, “Path/File access error.”

Private Sub RemoveFolder(ByVal strFolder As String) Static blnLowerLevel As Boolean ' A recursive call - no ' need to prompt user Dim blnRepeated As Boolean ' Use Dir state info on ' repeated calls Dim strFile As String ' File/Directory contained in ' strFolder ' Delete all files Do strFile = Dir(strFolder & "\*.*", _ VbNormal Or VbHidden Or VbSystem) If strFile <> "" Then If Not blnLowerLevel Then If MsgBox("Delete files in directory " & _ strFolder & "?", vbQuestion Or vbOKCancel, _ "Confirm File Deletion") _ = vbCancel Then Exit Sub End If strFile = strFolder & "\" & strFile Kill(strFile) End If Loop While strFile <> "" ' Delete all directories Do If Not blnRepeated Then strFile = Dir(strFolder & "\*.*", VbDirectory) blnRepeated = True Else strFile = Dir( ) End If If strFile <> ...
