Right, par2 does as well [1]. My question is: what advantage does the freeze&#x2F;melt thing have?<p>It looks to me that freeze&#x2F;melt produces a larger file that contains the recovery blocks, while par2 stores the recovery blocks in a second file (or files).<p>If the recovery bits are stored at the end of the freeze&#x2F;melt file then you can still use your frozen file as long as your program doesn&#x27;t barf on extra data at the end, while the par2 approach doesn&#x27;t have that limitation.<p>[1] <a href="http:&#x2F;&#x2F;parchive.sourceforge.net&#x2F;docs&#x2F;specifications&#x2F;parity-volume-spec&#x2F;article-spec.html" rel="nofollow">http:&#x2F;&#x2F;parchive.sourceforge.net&#x2F;docs&#x2F;specifications&#x2F;parity-v...</a>
