FileSeriesDeltaPacker

FileSeriesDeltaPacker was designed to be a simple command line tool that prepares a series of files so that the files may be compressed much better using e.g. tools like gzip.

It works best, when the files are similar. Imagine you are rendering an animation, then you get hundreds of single graphic files in an umcompressed format like TGA, BMP or RAW. The files all have the same structure.

Usually the differences from file to file are small. Either the compression of these raw files is ineffective as the packer does not recognize the similarity between the files and codes the same data several times (e.g. by converting the files to PNG or using gzip to compress the files) or it is effective (e.g. by placing the files into an AVI) but lossy.

FSDP can be a compromise between both: It can lead to better compression rates than the filewise compression and works lossless.
