Finding Files In A Directory

I have the following


Sub test()
Set fs = Application.FileSearch
With fs
.LookIn = "\directory"
.Filename = "3000333"
If .Execute > 0 Then
MsgBox "There were " & .FoundFiles.Count & _
" file(s) found."
For i = 1 To .FoundFiles.Count
MsgBox .FoundFiles(i)
Next i
Else
MsgBox "There were no files found."
End If
End With
End Sub

It looks into a specific directory, and tells me how many files beginning with 3000333 there are in that folder. I have over a thousand files in the folder, 13 of which begins with 3000333. However, according to this code, it only finds 10. After searching for various different strings, I've found out that it doesn't search for any file that has a modified date later than 6/2/2006. However, if i just use .Filename = "3000333" , that is, search for all the files in the directory, I get all the files, even those that were modified later than 6/2/2006 that I could not previously find.
