How to access Program Files folder via ASP.NET MVC

Question

We have to access Program Files folder (for read/write operations) from our ASP.NET MVC application.

As you can guess; Windows doesn't allow that. I tried to give full control access permission with user ASPNET (ASP.NET Machine Account) to the folder and files manually as suggested in .NET error log, but it's not working.

IIS: Version 8.5.9600.16384 @ Windows 8.1 x64
Pipeline Mode: Integrated
Application Pool: Custom ( Our custom application pool )

**Here is the .Net Error Log:**





  Access to the path 'C:\Program Files (x86)\DENEME\DENEMETEXT.txt' is denied.
  
  




  Server Error in '/' Application.

             Access to the path 'C:\Program Files (x86)\DENEME\DENEMETEXT.txt' is denied. 

  

             Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

            



             Exception Details: System.UnauthorizedAccessException: Access to the path 'C:\Program Files (x86)\DENEME\DENEMETEXT.txt' is denied.


ASP.NET is not authorized to access the requested resource. Consider granting access rights to the resource to the ASP.NET request identity. ASP.NET has a base process identity (typically {MACHINE}\ASPNET on IIS 5 or Network Service on IIS 6 and IIS 7, and the configured application pool identity on IIS 7.5) that is used if the application is not impersonating.  If the application is impersonating via <identity impersonate="true"/>, the identity will be the anonymous user (typically IUSR_MACHINENAME) or the authenticated request user.


To grant ASP.NET access to a file, right-click the file in File Explorer, choose "Properties" and select the Security tab. Click "Add" to add the appropriate user or group. Highlight the ASP.NET account, and check the boxes for the desired access.
