Abstract

Two or more separate physical file system directories are presented as one merged (virtual) file system directory to a process running in a silo. The operating system controls the level of access to the files in the merge directory. The operating system provides the merged view of the file system directories by monitoring file system requests made by processes in silos on a computer or computer system and in response to detecting certain types of file system access requests, provides the view of the seemingly merged directories by performing special processing. The types of requests which trigger the special processing include: enumeration, open, create, rename or close.
