Description

DF SDK is a Software development kit which provides an effective approach of creating software patches and updates, and integrating of the patch applying and/or building process directly into you own software product(s). Unlike other available products, DF SDK does not simply create incremental updates and re-package files, but analyzes each file at the byte level and builds the difference for updating the target file on the end-user’s system.

Using DF SDK you can effectively accomplish the following tasks:

• Software updating/patching to ensure your end-users always have the latest version of your software product;
• Differential data backup for effective backup data storage in a reliable yet space-saving way;
• Version control for reliable yet efficient control under versions of your files (of any type).

DF SDK does not deal with any specific data structures, it operates with files as a binary data, and thus designed to work well on files of any type including executables, libraries, data files and others. DF SDK can be used to build a compact byte-level difference for two binary files with the following reconstruction of the new version file(s) using an old file and the result difference file on the target machine.

Available as a standard dynamic link library (DLL), DF SDK can be used almost with any Windows development language. The DF SDK API is designed to be simple enough to integrate it into your existing products/solutions, and to provide a high-grade of performance and flexibility. DF SDK comes with sample programs, and includes examples whick can simplify patch creation and applying.

The size of your files, database or document doesn’t matter - only difference between versions does.

Description

Make Update and Update are a set of applications to update an older version of a file (or files) to a newer version. They work by finding just the differences between the two versions and applying those differences to the older version.

This is especially useful when you need to maintain common versions of large files at remote locations and the differences between the two versions is small. Another use is to "patch" files or applications -- that is, to provide updates of files (e.g., applications) to current users without making the contents of the entire files available others.
