Hi VJ,

It seems you have 2 different problems to solve here:

1. Let the application access only C:\MyApp folder and subfolders

2. Protect the content of the files from other users

For 1, if your application is managed, then it's really easy, you can modify
the .NET security policy to grant this application access to only this
folder. Where is the application running from? If it's running from My
Computer, then it will be able to do whatever it wants since it will have
FullTrust by default. If not, did you consider using IsolatedStorage?

Problem 2 can be solved using Windows security by giving access to the files
only to the users you trust.

Please let me know if you have any other question. Thanks,
Marcelo
