Using two corrupted archives to create a fixed one



  • i downloaded a rar file and got it corrupted. I downloaded it again, and got it corrupted again. I’m convinced that the original file is not corrupted.
    So I have two corrupt archives in my computer. Isn’t there a tool to create a repaired archive using the two corrupt ones? I mean, if my two archives are corrupted in different ways, can I somehow merge the two corrupted archives to create a repaired one? Is there any tool that does this?



  • Is there also a .par2 file?



  • If you open PowerArchiver, you will notice their is a button called Repair Archive you then click that and select the file which is corrupt.

    See if that works.



  • @Sir:

    If you open PowerArchiver, you will notice their is a button called Repair Archive you then click that and select the file which is corrupt.

    That is only for ZIP archives - PA cannot repair RAR archives, you need WinRar (or RAR command line) for that!
    :rolleyes:



  • I have tried the repair buttons from both PA and WinRAR, but they haven’t worked.

    My question is whether there is some way to merge two corrupted versions of the same archive to create a repaired one.



  • The only way to repair “corrupted” files, is to have some extra “correction information”. This may be included in the archive when the RAR was created in which case RAR repair would be used. If not, then you would need other information e.g. PAR2 as suggested by Guido.

    With neither, all you can do is download again (and again) until you get a good file.



  • Maybe you could try a download manager an re-download the file.
