File laast accessed by user- CIFS share

Hello everyone,

I needed to know as to when a given file was last accessed.

We have a File System with sub directories that is shared by multiple users using CIFS protocol - 7 Model. I needed to know as to when they were last accessed. Please help.

What we are planning to do it to archive the sub-directories that are not accessed for a long time.

Thanks again from the help!

Much appreciated.
