then u can do:

if IO.File.exist("path and file here") then
io.file.delete("path and file here")
end if

Private Sub RemoveDir(ByVal _path As String)
        For Each mDir As String In IO.Directory.GetDirectories(_path)
            My.Computer.FileSystem.DeleteDirectory(mDir, FileIO.DeleteDirectoryOption.DeleteAllContents)

Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button3.Click
		Dim strDir As String = "C:\testdir\"
		If (System.IO.Directory.Exists(strDir)) Then
			Dim dir As New System.IO.DirectoryInfo("C:\testdir")
			Dim files As System.IO.FileInfo() = dir.GetFiles()
			For Each file As System.IO.FileInfo In files
				System.IO.File.Delete(file.FullName)
			Next
		End If
	End Sub

when a file is uploaded by a user it is stored in a folder.. if he uploades other file in the same folder, the file which was already uploaded by him should be deleted and newly uploaded file must be saved.
files are uploaded by users.. so we dnt know the filename..

if System.IO.File.Exists("fileName") then System.IO.File.Delete("fileName") then save the new file just like you did before when it didn't exist.
