Output File Xdelta |top| Access
Unlike standard compression tools (like gzip or zip ) which contain the entirety of the compressed data, an XDelta output file is structurally dependent on the source file. It contains only the changes (deltas) and copying instructions. This results in significantly smaller file sizes when differences between versions are minimal.
To create a delta between original_file and updated_file , use: xdelta3 -e -s original_file updated_file output_patch.xdelta -e : Encode (create the patch). -s : Source (the base file you are comparing against). output_patch.xdelta : The resulting difference file.
