Yes. "Par" as in parity. The par files would contain redundant
information which is intended to be used to verify/repair broken file(s)
(not necessarily rar files). Essentially the same as Forward Error
Correction.

If you have incomplete or damaged files then you need par files to
repair. Can not create par files out of bad files.
