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, fax, or email the digital file, the virtual machine creates, from the digital file existing in an original format, a copy of the digital file in 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 the copy of the digital file, send a facsimile of the copy of the digital file, or email the copy of the digital file. The host OS may consult policy data in determining how to carry out the request vis-à-vis the digital file.
