- ronjouch 5y agoI'm sure there is a public algorithm / implementation. My question here is: is there an existing archive format (like .7z) that integrates it to the archive format and knows to update the error-correction data on archive update? Maybe not in a way that is as user-friendly as RAR, but "halfway there". Or are you suggesting all my .7z files should come with a sibling .par2, that I must remember to regenerate after every change of the .7z ? I know I was asking here about "Usability-aside alternatives", but that alternative seems quite inconvenient and below the bar I was ready to accept when asking for less-user-friendly stuff.
- ronjouch 5y agoA by-the-way note for passerbys on the subject of PAR recovery records: - As usually, the Arch wiki has an excellent page on the topic: https://wiki.archlinux.org/title/Parchive https://wiki.archlinux.org/title/Parchive - Hey, par3 is in the works: https://github.com/Parchive/par3cmdline/issues/1 https://github.com/Parchive/par3cmdline/issues/1 - I created [Feature request / par2create] Option to regenerate par2 files if input file changed : https://github.com/Parchive/par2cmdline/issues/170 https://github.com/Parchive/par2cmdline/issues/170
- ASalazarMX 5y ago> Reed-Solomon error correcting codes Had to double check that. I would have sworn those codes were called Solomon-Reed, not Reed-Solomon. Guess I have my little Mandela Effect now!
