Downloading XDeltaEncoder 1.0 for Mac from the developer's website was possible when we last checked. We cannot confirm if there is a free download of this app available. The software belongs to Developer Tools. The actual developer of this free software for Mac is Frantisek Mantlik. We recommend checking the downloaded files with any free antivirus.
From the developer:
XDeltaEncoder is a tool for creating and manipulating binary delta patches. Binary delta is a file representing the difference between the old and new version of a binary file. With the use of the delta patch, new version of the binary file can be reconstructed (decoded) from the original old binary file.
You may want to check out more Mac applications, such as Objective Basic, Pleinpot or Epsilon, which might be similar to XDeltaEncoder.
