Even though PatchFactory technology can be implemented in just a few minutes, the resulting benefits are numerous and long-lasting. Some of the key benefits and advantages of integrating PatchFactory into your application development and supporting process are listed below.

Improved technical support and customer satisfaction:
Unlike setup files, which contain all files needed to run the software, the result update program only contains information concerning modifications (including changes in files/folders structure) made to old version software files relatively to new version files and has an easy-to-use interface with user-friendly dialogs.

PatchFactory analyzes the original and updated file at the byte level, generating the smallest size patch file required to perform the update. This results in a significant reduction in the size of the patch, which translates into lower bandwidth usage, shorter download times and increased reliability. Patches are smaller comparing to competitors thanks to improved byte-level patching engine. The small patch file footprint makes it an ideal tool for updating in a bandwidth-sensitive environment.

The patching engine is not content dependent, so it may be used whenever data is changed at one location and must be efficiently updated at another.

PatchFactory is more than just a byte-level differencing tool - it is a complete software update solution. From the building, to the distribution, to the patch applying, to maintaining the patches on your end-user's computer, PatchFactory provides major features that give you the ability to fit the update process to your specific needs.

Unlike re-packaging or creating incremental updates, generating a patch does not require the developer to create another program or modify an existing script (such as an InstallShield installation script) for each update that is released.

With the ability to easily generate version-to-version and cumulative patches for updated software, there is no reason to keep customers waiting for the next version. Your customers always have the latest version of your software, reducing the number of technical support issues for those defects which have already been corrected.

Using PatchFactory it is possible not just to create one patch for a certain software version, but also visually maintain all your software products, product versions and version components that may have different location on the end-user's machine. Innovation is based on the advanced functionality of the new release that includes Version tree, Miltiple version Components support, Inheritance of properties within product versions and Difference Manager.

Lower media and distribution costs: Go back to the top of the Current Page
The ability to distribute a small patch, rather than re-packaging the complete product, can significantly reduce the costs associated with creating and shipping media. In addition, the smaller size of the patch files means bandwidth savings when making the update available for download.

Once a new version of your application is available, it only takes a few minutes to create an update from the previous version to the current one. You can release software updates as often as you require.

Because the updates are published directly on the Internet, you do not need to create and distribute expensive physical media. The small size of the update files also results in lower bandwidth requirements and reduced deployment costs

Because all of your customers are using the same version of your software, PatchFactory effectively eliminates the need to provide technical support for outdated versions of your application.

Safety and security: Go back to the top of the Current Page
The patching process is designed to be completely safe, committing the update only if no problems are encountered during the process. The original and updated file version, checksum and digital signature (if any) are checked to ensure that the file was patched correctly.

Because the patch consists only of the changes to a file, it requires that the user actually have the software installed on their system, thus PatchFactory can help protect against illegal distributions of updates for your software. Files that have been tampered will not be updated.
