PA 2110 11.50.23 - Corrupted archives

  • PA_Fan

    Win XP Pro SP3

    I have a number of Zip archives which were either created or updated using PA 2009. Sizes vary but may be 50 mb, and some a lot smaller. None have given problems. I am now working with them using PA 2010.

    In one archive, I have 97 files, of which 6 are DFLT-X and the rest DFLT-N. The files are almost all PDFs.

    When I click them to view in Acrobat, I often get a blank error window across the centre of the screen and the PA status bar shows corrupt characters. Other files perform as expected, but I can see nothing to differentiate them from the faulty ones. This also happens when attempting to preview.

    When I test the archive, I get a message requesting a password several times (none of the files are thus protected and nor is the archive). The test proceeds to end and reports 45 errors in the archive. The test display shows "Testing: "then a mass of corrupt data and at end “–> CRC error”.

    This happens with some, but not all archives - though I have a lot hand haven’t checked them all.

    I am currently testing a possible temporary fix by extracting files from backup archives and creating entirely new archives under 2010 - but this is palliative only.

    Sorry about 2110 typo!

    I can supply screenshots but they are too big to attach. If required, I’ll email them.

    I am definitely updating archives (created under 2009 or before) either by moving new files to them or adding or updating.

    I have found that in some instances I can repair (via PA) my archive with minimal file loss; but in others anything up to 1/3 are corrupt.

    I’ve downloaded and installed this .26 version.

    Can you please tell me what it is meant to fix?

    I’ve tried working (including repairing) on a corrupt zip with the latest version but everything happens as before i.e. files are corrupt on view, open and extract, and the archive cannot be repaired.

    If it’s not a retrospective fix, then I imagine that it is intended to stop the problem happening again in future.

    yes, it is meant to stop future issue, however it can not fix already corrupted archives…

    Thanks for that information.

    So far as I can make out, the new version is going OK.
