Hi Haridas. I'm Greg, 10 years awarded Windows MVP, here to help you.
What makes you think these files are stored in Program Files, that would be highly unusual since only the actual program files that run the program get installed there. Program Data usually goes to a folder like hidden C:\Program Data, or one of the hidden AppData folders under your User Account. Some apps also let you set where you want the files created in the app in the the app's Settings.
Did you research where the files create by the App are stored? Did you check the app settings to see if this is shown or can be set there?
If you'll tell me the name of the App I can help you determine this.
Feel free to ask back any questions. Based on the results you post back I may have other suggestions if necessary.
