This is all assuming that the portion of the file that got corrupted ISN'T the portion storing the checksum data.

You don't "use up" a PAR. It's not a bandage, or a tissue. It's perfectly possible to restore more than one file with one PAR. (Depending on the total number of parts in the archive set and the total number of PAR's included.) --snip-- > I'd say that's pretty much a certainty.

Thanks. I don't believe I ever began "blasting" a piece of software. What I did was refute YOUR assertion that RAR is superior to a combination of free software tools that performs a nearly-identical function. If you want to use a non-free archiving utility, you are quite welcome to do so. Just don't state AS FACT your OPINION that an equivalent result cannot be obtained using different tools. I'm very familiar with the RAR program and its evolution over the last 10+ years, including the new features that 3.0 introduced. My question, as before, remains what practical benefit this software presents that CANNOT be achieved otherwise? -- Alex Malinovich Support Free Software, delete your Windows partition TODAY!
