Using CMD for access permissions?

[Ultraviolet]

I'm trying to use this code to grant the current user full permissions to access System Volume Information:

//It works when manually written in cmd
cacls "E:\System Volume Information" /t /e /g %username%:F



    //but using this formula to make the command window hidden does not work(doesn't give the permission or hide the window)
Process^ P  = gcnew Process;
P->StartInfo->FileName = "cacls.exe";
P->StartInfo->Arguments = "cacls \"E:\\System Volume Information\" /t /e /g %username%:F";
P->StartInfo->WindowStyle = ProcessWindowStyle::Hidden ;
P->Start();

The code compiles but doesn't work.

Could anyone please give the right code please?

cacls is depreciated. Use icacls and see if that works for you.

Sorry for the late answer. I used icacls but it gives me the same cmd error:

It says that the path(E:\System Volume Information) is an invalid parameter.

Is there anything else I can do?

thanks
