There is an example here:

http://msdn.microsoft.com/en-us/library/fxeahc5f.aspx
Directory.Delete Method (String, Boolean)

You can specify the My.Computer.FileSystem.GetFiles() to be a string. More info is here.

Dim strDirectory As String = "C:\Folder\Folder"
For Each foundFile As String In My.Computer.FileSystem.GetFiles(strDirectory, "*.*")
   My.Computer.FileSystem.DeleteFile(foundFile, FileIO.UIOption.AllDialogs, FileIO.RecycleOption.DeletePermanently)
Next

Read this note there :

Use the My.Computer.FileSystem.GetFiles method to return the collection of strings representing the files in the directory.

It depends on you how you want to input path. Your options are :

Using a FolderBrowserDialog.

Example :

Dim path as string

If FolderBrowserDialog1.ShowDialog() = DialogResults.Ok Then

path = FolderBrowserDialog1.Selectedpath

End if

Now path variable holds user selected path. Put it as argument for GetFiles()

If you want to hardcode path. You can anytime put it has getFiles("C:\MyFolder")

If you want folder relative to your application installation directory, you could do it like

path as string = Application.StartupPath & "\yourFolder\anotherFolder"

pass path variable to getFiles() method.

Just change the parameter for the my document to directory you want to remove. You can use FolderBrowserDialog to get the path and pass the name to the code.

Dim fb as new As New System.Windows.Forms.FolderBrowserDialog

If fb.ShowDialog=Windows.Forms.DialogResult.OK Then
For Each foundFile As String In My.Computer.FileSystem.GetFiles( _
fb.SelectedPath,FileIO.SearchOption.SearchAllSubDirectories, "*.*")

    My.Computer.FileSystem.DeleteFile(foundFile, _
        FileIO.UIOption.AllDialogs, _
        FileIO.RecycleOption.DeletePermanently)
Next

End IF

Another way that you can do it is this: If you want to delete everything in the folder, why not just delete the entire folder, then turn around and rebuild it. I do that often with temp folders that I create:

    If My.Computer.FileSystem.DirectoryExists(tempZipFolder) Then
      My.Computer.FileSystem.DeleteDirectory(tempZipFolder, FileIO.DeleteDirectoryOption.DeleteAllContents)
    End If

    My.Computer.FileSystem.CreateDirectory(tempZipFolder)

 My
.Computer.FileSystem.DirectoryExists(tempZipFolder) Then

   My
.Computer.FileSystem.DeleteDirectory(tempZipFolder, FileIO.DeleteDirectoryOption.DeleteAllContents)
  End
 If


  My
.Computer.FileSystem.CreateDirectory(tempZipFolder)

Do not ignore

FileIO.SearchOption.SearchAllSubDirectories parameter passed to GetFiles()

what if there's a complex folder structure inside ? how would you get it back ? Using that parameter you could delete all the files matching to specified filter and keeping folder structure as it is :-)

okeyy....i cant do rmdir cause that wont delete the files insideIf you don´t Believe in it, Then it Doesn´t Exist!

_{Friday, April 23, 2010 7:06 PM}

@ Omie ->

Good point there. I wasn't thinking as all of my 'temp files' are all simple subfolders I create from the user's application folder.

You cant do what? Try to typing out the word. This is not social network where people get lazy to typing out simple word and forum does not have characters limit.

There is some weird stuff showing up in the help files lately. VB has enhanced file and directory handling. Use DeleteDirectory.

_{Sunday, April 25, 2010 10:05 AM}

How do i use DeleteDirectoryIf you don´t Believe in it, Then it Doesn´t Exist!

Frank has already given you friday a complete sample on you in this message thread.

That would be my first approach also.
