Help....        Must Maintain Directory and Files LastAccessedTime

I have to search thru massive directory trees including all files within. I have one issue using the (Directory | DirectoryInfo | DirectoryInfo[] and the File | FileInfo | FileInfo[] )
They all mod the LastAccessedTime !!!! ANd the only property I need happens to this....  So if I look at it today and it was 10/5/1999 right after I look at it, it becomes DateTime.Now !! Grrrrrrr :)

I am probably overlopoking something simplistic but as it stands I need help fast....   Thanks in advance BillyDvd
