用于创建和gdiff格式的二进制增量文件可以处理任意大小的文件操作的java包。

Introduction XDeltaEncoder is a tool for creating and manipulating binary delta patches. Binary delta is a file representing difference between 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. XDeltaEncoder uses GDIFF patch format specified in http://www.w3.org/TR/NOTE-gdiff-19970901.html XDeltaEncoder is based on modified Javaxdelta libraries. For more information about Javaxdelta project please visit http://javaxdelta.sourceforge.net. On this page: Usage Create delta from source and target java -Xmx2048m -jar XDeltaEncoder.jar [options] source target delta When source is very large - several Gb, use e.g.: java -Xmx1500m -jar XDeltaEncoder.jar -p -b 500m -tb 500m -bt 5m -c 20 source target delta Decode target from source and delta
