Efficient virtual application update

摘要

Efficient virtual application updating is enabled. An old version of a virtual application can be compared to a new version of the virtual application and updated as a function thereof. A file unchanged from the old version to the new version can be hard linked from the new version to the old version. For a changed file, matching portions of the file can be copied from the old version to the new version, and remaining un-matching portions can be acquired from another source.
