VS.NET 2003: MACRO - Cleanup temp web folder when closing

This problem has got to annoy at least someone as much as it annoys me:

You close a Web project and open another than has a similar folder structure
You attempt to create a folder that existed in the previous web project but not in the new one.
Visual Studio tells you that the folder already exists
You swear and delete everything in c:\Documents and Settings\[Username]\VSWebCache\[ComputerName]
You close and open the project
You create the folder

To solve this annoying problem, I came up with an EnvironmentEvents macro a while back that cleans up the VSWebCache folder when you close a solution that contains a web project. To implement, paste the code below into a EnvironmentEvents macro module.

    Private PerformCleanup As Boolean

    Private Sub SolutionEvents_AfterClosing() Handles SolutionEvents.AfterClosing

        If (PerformCleanup) Then
            Dim psi As New ProcessStartInfo("cmd", "/C rmdir /Q /S ""%homedrive%%homepath%\VSWebCache\%computername%""")
            psi.CreateNoWindow = True
            System.Diagnostics.Process.Start(psi).WaitForExit()

            psi = New ProcessStartInfo("cmd", "/C mkdir ""%homedrive%%homepath%\VSWebCache\%computername%""")
            psi.CreateNoWindow = True
            System.Diagnostics.Process.Start(psi).WaitForExit()
        End If
    End Sub

    Private Sub SolutionEvents_BeforeClosing() Handles SolutionEvents.BeforeClosing
        Dim isWebProject As Boolean = False

        Dim prj As Project
        For Each prj In DTE.Solution.Projects
            If (prj.Properties.Item("ProjectType").Value = 1) Then
                isWebProject = True
                Exit For
            End If
        Next

        PerformCleanup = isWebProject
    End Sub
