JDIFF is a program that outputs the differences between two binary files,
|
||
|
|
either in binary format or human readable format (detailed or summarized).
|
||
|
|
JPTCH can then be used to reconstruct the second file from the first file.
|
||
|
|
|
||
|
|
Possible applications include incremental backups, synchronising files
|
||
|
|
between two computers over a slow network, and others.
|
||
|
|
|
||
|
|
JDIFF tries to find a minimal set of differences between two files using
|
||
|
|
a heuristic algorithm with constant space and linear time complexity.
|
||
|
|
This means that accuracy is traded over speed. JDIFF will therefore, in
|
||
|
|
general, not always find the smallest set of differences, but will try
|
||
|
|
to be fast and will use a fixed amount of memory.
