phpar2 is an advanced "par2cmdline" with multithreading and highly optimized assemblercode (about 66% faster than "QuickPar" 0.9.1).
It is a command-line tool to create and utilize parity files for a set of source files, enabling one to repair the source files in case they are damaged, perhaps in transmission or due to the aging of some storage system.
Available in 32 & 64 bits versions, there IS support for windows XP.
