SDK code to copy report to different folder

[srini_in72]

Hi,

I have requirement like this.

I developed couple of reports using cognos8.3. My reports run multiple times in a month. When we save report views, they save with different timestamps. I wanted them to be moved to one folder either in portal or to local machine.After moving them to different folders, i wanted to keep only first and last versions of my reports in a month.
Is there any SDK or java script or event studio code with which i can keep first and last versions of my report in a different.
If so could you please provide me with that code.
