&nbsp;<BR>I am trying to create a file management system that detects when files are being accessed and who last saved them.<BR><BR>As far as I can see, the file attributes as available through the FileSystem object do not change when a file (eg. .xls) is being accessed.<BR><BR>However, the system knows that the file is open as it is only available to other users as Read-only.<BR><BR>How can I detect when the file is open?<BR><BR>Also, I noticed that NTFS logs who saved the file last (in properties) when dealing with .xls etc. How can I detect this using ASP?<BR><BR>Thanks for any help - I&#039m stumped!
