[2005] Delete old files

[simonp]

Hi,

My app lets you download backup files from the Internet and save them locally.

I want the app to be able to automatically delete old backups though. What's the best way to do this?

So if I allow the user to store five files named:

backup-03-03-2009.zip
backup-04-03-2009.zip
backup-05-03-2009.zip
backup-06-03-2009.zip
backup-07-03-2009.zip

When backup-08-03-2009.zip is downloaded it should delete backup-03-03-2009.zip and so on.

Any tips/advice welcome!

Thanks

Simon

Something like this, but obviously you should test it out:

        Dim files() As String = IO.Directory.GetFiles("C:\Temp\backup")
        For Each f As String In files
            Dim filenamedate As String = f.Substring(f.Length - 14, 10)
            Dim dt As DateTime
            If Date.TryParse(filenamedate, dt) AndAlso DateDiff(DateInterval.Month, Now.Date, dt.Date) < -5 Then
                IO.File.Delete(f)
            End If
        Next

Ah - I see what you've done there. Unforuntately, the files won't always be called the same

Can I get file attributes in vb.net? Eg the 'Created' date/time?

Sure, you can use IO.File.GetCreationTime to get the creation time of a file.
