qpress

If you're in the market for a reliable file archiving software, qpress is a great option to consider. This portable tool has been developed using QuickLZ and is designed to provide users with the ability to maximize the performance of fast storage systems. In fact, qpress is often faster than traditional file copy methods because of the significantly reduced size of the destination file.

One of its greatest features is its ability to support multiple cores, allowing you to reach up to 1.1 Gbyte/s in-memory compression on a quad core Xeon. It also supports 64-bit file sizes and has been tested with terabyte-sized archives containing millions of files and directories. Additionally, the software boasts pipes and redirection, and *nix-like behavior, adding to its scripting and flexibility.

To ensure that decompressed data has not been corrupt, qpress utilizes Adler32 checksums. Moreover, in the case of data recovery of damaged archives, the software has the ability to repair them with 64 Kbyte granularity. Finally, Windows users will appreciate the software's unbuffered disk I/O, which prevents the disk cache of other applications from being flushed.
