Dear Experts,

From what I have gathered it seems possible to read a file 'Sector wise' using CreateFile() irrespective of whether if it is 'Opened' by another user eg: Outlook.pst.

Question: What happens if that the file gets written into. How can I take point-in-time copy the file,
(without using VSS).

I use Delphi 2007, Windows XP.

Regards
Allan Fernandes

In my application I want to take incremental backups of files. With VSS I need to Shadow the entire Volume (some programmers have managed to do differential backup of just specific files) but it cannot be incremental all the same.
