Abstract
Approaches for processing a digital file in a manner designed to minimize exposure of any malicious code contained therein. A digital file resides with a virtual machine. When the virtual machine receives an instruction to print or digitally transfer at least a portion of the digital file, the virtual machine converts at least a portion of the digital file from an original format to a different format within the virtual machine. The different format preserves a visual presentation of the digital file without supporting metadata or file format data structures of the original format. The virtual machine instructs the host OS to print or digitally transfer the portion of the digital file. The host OS may consult policy data in determining how to service the instruction to print or digitally transfer the digital file.
