I have been cleaning up files on my laptop, and moved a number of files to my ex hd.
I then created archive files of each one, using File > Create Archive.
All went fine - but when I went back to check each archive file, I found that one file cannot be opened. When I click on the archive file the process seems to run normally almost to the end, at which point I get a dialogue box reading "Unable to unarchive 'filename.zip' into 'foldername'. (Error-1 - Operation not permitted.)
I dragged the file from the ex hd to my laptop desktop and tried it there, but with the same result. Now I have no access to these archived files.
Is there a way to repair this?? The files are stored, but I will need access to them at some point. Recreating this archive would involve a great deal of work downloading copies of every file from a remote server, so I hope that's not necessary. Do I have any options? Can the archive file be repaired??

    I wonder if one of your drives is Formatted "Case Sensitive"?

    You do have plenty of free space for it to work?

    I'd give a try with Zipeg...

    Hello BDAqua:

    How would I check to see if my external drive was formatted that way? I've never had any problems before, either archiving or opening archived files.

    I have 10.2 GB available space on the ext hd, 11.13 GB available on the laptop.

    Also, the problematic archive is 328.8 MB; a larger archive, at 432.8 MB, un-archived and opened without a problem.

    I'll try Zipeg.

    No luck with Zipeg.

    Message: Failed to open "filename"
    unsupported format

    Is it possible that I have just lost ALL those files in that archive file?? OMG...

    Yay! The UnArchiver worked like a dream. New archive will now open normally with both Unarchiver and the Archive Utility. Thanks SO much.

    Also, as long as I have your (virtual) ear: I did run both Disk Utility and Disk Warrior, just in case, and rebuilt directory in DW.

    On my laptop hd, Disk Utility reported "Disk passed verification". But it seems to me that this message from DU used to read: "The disk appears to be ok."
    Is this a step down, and does this mean that my disk is in fact starting to show some problems? Or has the basic "ok" message from DU changed?

    The report from DWarrior reads: "This hard drive's built-in SMART diagnostics indicate the drive is functioning normally." Does anything here indicate problems?

    Here's what I get from DU in 10.4.11, both...

    Verifying volume “SG250”
    Checking HFS Plus volume.
    Checking Extents Overflow file.
    Checking Catalog file.
    Checking multi-linked files.
    Checking Catalog hierarchy.
    Checking Extended Attributes file.
    Checking volume bitmap.
    Checking volume information.
    *The volume SG250 appears to be OK.*
    Mounting Disk

    1 HFS volume checked
    *Volume passed verification*

    The report from DWarrior reads: "This hard drive's built-in SMART diagnostics indicate the drive is functioning normally." Does anything here indicate problems?


    No, that is a good report.

    Ooog, apparently some serious tunnel vision on my part. I just didn't see the line somehow - but yes, my report from DU looks exactly like yours. Sorry sorry.

    But thanks, BDAqua, for all your help - and particularly the Unarchiver solution, which saved me from hours of rebuilding! The forums come through, as ever.
    thx
