Rename a file

Hi,

I get a text file daily which is comprised of the date so the name of the file changes daily.  For example, 030705asl.txt and 030805asl.txt etc...  How can I rename this daily file to just asl.txt?   I have tried the file.copy but apparently wildcard characters do not work.

Hi.. i test this code and it works...

        Dim di As New IO.DirectoryInfo("D:\My Documents\Test\")
        Dim fi As IO.FileInfo

        For Each fi In di.GetFiles("*asl.txt")
            MsgBox(fi.Name)
        Next

=============

so you can change it to something like

        Dim di As New IO.DirectoryInfo("D:\My Documents\Test\")
        Dim fi As IO.FileInfo

        For Each fi In di.GetFiles("*asl.txt")
            Dim newFilename As String = fi.DirectoryName & "\asl.txt"

            If IO.File.Exists(newFilename) Then
                'that name exists
            Else
                fi.MoveTo(newFilename)
            End If
        Next

An alternative is this... this strictly tests for files with the pattern ######asl.txt where # is a number (I think my previous example would have picked up "asl.txt" as well, this one is stricter... you could even be more strict by making sure its a valid date! )

        Dim di As New IO.DirectoryInfo("D:\My Documents\Test\")
        Dim fi As IO.FileInfo
        Dim patternTest As New System.Text.RegularExpressions.Regex("\d\d\d\d\d\dasl.txt")
        For Each fi In di.GetFiles()
            If patternTest.Match(fi.Name).Success Then
                Dim newFilename As String = fi.DirectoryName & "\asl.txt"

                If IO.File.Exists(newFilename) Then
                    'that name exists.. do what you like here... either overwrite or alert the user
                Else
                    fi.MoveTo(newFilename)
                End If
            End If
        Next
