. Located in Winnipeg, Manitoba, CanadaWhat is Visual Patch?
. A software development tool for creating self-
applying patch files
. Lets you patch software from one version to another
in a secure and efficient manner
. Uses binary differencing algorithms to create the
smallest patch files possibleBinary Patching
. Creating a binary patch involves performing a byte-by-byte comparison
between the original file and the new file, and then encoding the
differences into a difference file
. Each difference file contains the actual bytes that are different in the
new file, along with a number of instructions that describe which bytes
need to change, and which bytes are the same. This information is said
to be encoded into the difference file.
. When the patch is applied, the difference file is decoded, and the
instructions are used to build the new file by copying the "unchanged"
data out of the old file, along with the "changed" data that was
encoded into the difference file.Benefits of Binary Patching
. SMALLER FILES: Since only the differences are included in the patch,
space savings can be up to 99% over including the entire file in an
installer.
. REDUCED BANDWIDTH: Smaller patch files result in reduced
bandwidth costs.
. SPEED OF DELIVERY: Smaller files means that customers are able to
download patches faster.
. SECURE: The best way to protect information during transmission is to
never transmit it in the first place. By only transmitting the data that
has changed, patches reduce the risk of third-party interception.
. DATA INTEGRITY: A patch can't update something that isn't there. If a
user doesn't already have your software installed, they won't be able to
apply the patch.How Does it Work?
