Refriender can be used to find and extract all the compressed blocks in a file, either with a single algorithm, a set of algorithms, or (the default) all of them. It can also find pointers to those blocks, or to just before the block, as is often the case with archive files. Additionally, libmagic can be used to identify the contents of decompressed blocks.
