qpress is a portable file archiver using QuickLZ and designed to utilize
fast storage systems to their max. It's often faster than file copy
because the destination is smaller than the source. A few features:

* multiple cores, reaching upto 1.1 Gbyte/s in-memory compression on a
quad core i7
* 64-bit file sizes and tested with terabyte sized archives containing
millions of files and directories
* pipes and redirection and *nix-like behaviour for scripting and
flexibility
* Adler32 checksums to ensure that decompressed data has not been corrupted
* data recovery of damaged archives with 64 Kbyte grannularity
