Check modification dates of apps on CD and on intstallation.
Act accordingly.

Hi ,
Thanks for ur reply.
But my problem is something else.
Here is the complete Description

I have a C#2005 application that we are providing to our clients.
We are providing data in the form of cab files
there are 2 cab files
the size of each cab file is round about 450 mb.
we provide monthly services .
hence some of the files are used to add each month.
but we provide the old data again and again also.
I want a method by which I can give only newly added or modified files at each time and merge those files into previously installed files.
is there any method to do so.
Thanks in advance.
I need urgent help.
