I have a directory with a lot of .log files, one for each day

how do I list just the 10 most recent files by file creation date, or, in other words, the files for the last 10 days?

Hi kapcreations:
I would start with code like this:

    Dim DirInfo As New System.IO.DirectoryInfo("")
    Dim Files() As System.IO.FileInfo = DirInfo.GetFiles("*.log")
    For Each f As IO.FileInfo In Files
         Save(f.Name, f.CreationTime())
    Next

Within Save you can create a SortedList and then keep only the most recent 10

Ignore the For Each loop above and use this code instead:

        Dim sl As New SortedList
        For Each File As IO.FileInfo In Files
            sl.Add(File.CreationTime, File.Name) 'Add file to SortedList. SortKey is CreationTime
        Next

        Dim Count As Integer = 0
        For Each File As IO.FileInfo In sl 'Now show the sorted list in correct order
            MessageBox.Show(file.Name & " " & file.CreationTime.tostring)
        Next
