Abstract: Securely performing file operations. A method includes determining a licensing characteristic assigned to a file. When the licensing characteristic assigned to the file meets or exceeds a predetermined licensing condition, then the method includes performing a file operation on the file in a host operating system while preventing the file operation from being performed in the guest operating system. When the licensing characteristic assigned to the file does not meet or exceed the predetermined licensing condition, then the method includes performing the file operation on the file in the guest operating system while preventing the file operation from being performed directly in the host operating system.

Abstract: Securely performing file operations. A method includes determining a trust characteristic assigned to a file. When the trust characteristic assigned to the file meets or exceeds a predetermined trust condition, then the method includes performing a file operation on the file in a host operating system while preventing the file operation from being performed in the container operating system. When the trust characteristic assigned to the file does not meet or exceed the predetermined trust condition, then the method includes performing the file operation on the file in the container operating system while preventing the file operation from being performed directly in the host operating system.
