Abstract
Generating a modified protected file is disclosed, including: creating a modified protected file at least in part by embedding a protected file into an at least partially unprotected file; and modifying a set of content type information included in the at least partially unprotected file to include a content type associated with the protected file as embedded. Using the modified protected file is disclosed, including: receiving, using a processor, a data access operation to an at least partially unprotected file; determining that the at least partially unprotected file includes a portion associated with a content type associated with embedded protected content; and redirecting the data access operation to the portion of the at least partially unprotected file associated with the content type associated with embedded protected content.
