EXPLICIT OVERLAY INTEGRATION RULES

摘要

A technique for controlling access to files or directories in a system that includes and overlay involves the use of explicit overlay integration rules. An example of a method according to the technique may include providing an overlay to a file system structure; providing an explicit overlay integration rule; and directing a file access for a file that resides in the file system structure and in the overlay to either the file system structure or the overlay depending upon the explicit overlay integration rule. The overlay may or may not be associated with a streaming software program. The proposed system can offer, among other advantages more control over access to files and directories in the file system/overlay.
