Cannot Open GZ Archive

  • D

    I am unable to open the archive at this location:
    http://the.earth.li/~sgtatham/putty/latest/putty-0.55.tar.gz

    I am given an error that says “Error in TAR/GZIP file structure” and another dialog box immediately after “DynaZIP-GT Error Problem with structure of GZIP/TAR file (Problem extracting files(s))”.

    This archive extracts fine on my linux machine with “gunzip putty-0.55.tar.gz” as well as “tar zxf putty-0.55.tar.gz”. However, once I gunzip the archive on my linux machine, the TAR archive opens without incident with PA.

    I am using PowerArchiver version 9.01.01 (August, 2004).

  • Also, PA test (via shell extension) shows:

    “Error in TAR/GZIP file structure” and another dialog box immediately after “DynaZIP-GT Error Problem with structure of GZIP/TAR file (Problem extracting files(s))”

    twice !

    Followed by the “All Files OK” dialogue :eek:
    I agree that “other” utilities can extract OK (under Win98).

    if you use winzip on this archiver wit will show the archive inside the first one (the tar one) but once you click on the tar one it sayes garbage in gzip file, decompression ended. Basically it means either a corrupt archive or wrong/ incorrect file names. However you can click on the tar file and it will open up in either winzip or poweratrchibver depends on what proigram is associated with tar files.

    In my opion better error catching and handling in needed like winzip for powerarchibver, though its not totally its fault its a faulyty archive naming thats at fault.

    Powerarchjiver should have been able to work round this problem like winzip did.

    PA does need better error handling/reporting.

    However, that doesn’t explain why only PA and Winzip have problems with the file.
    Other utilities are able to extract this file OK e.g. 7-Zip (among other windows programs) and Gunzip(Linux) according to DaCypher.

    I thought PA showed 2 error messages here? Reason why PA and WinZip show errors is because…. there is an error in gzip archive.

    It is quite possible that other utilities dont check headers or just ignore the error.

    Well, PA-Extract shows Four error messages (The two error messages are repeated).

    PA-Test shows the same four error messages - followed by “All files OK” :p

    I assume that these repeated messages are caused by

    1. Gzip (header) - first pair
    2. Tar (access fails because of Gzip header) - second pair

    Not sure what the “All files OK” message means.
    But this is confusing - that is what I meant by “does need better error handling”.

    There is an error in the gzip archive? I guess its not serious enough to cause a failure of file extracting as gunzip has proven to not have any problems with it. If there is an error in the archive, maybe a notification to user of this and then continue to extract it as this appears to be feasible?

    On another note, I tried extracting this archive on my freebsd machine and got this:
    $ gunzip putty-0.55.tar.gz

    gunzip: putty-0.55.tar.gz: decompression OK, trailing garbage ignored

    Not sure if this is due to a different gunzip or what. Either way, the current PA behavior with this archive seems like it could be handled a little better. 🙂

    Thanks!

    I found the problem with .GZ file with garbage and our GZIP engine. I have addressed this problem for version 9.1.

    In the meantime I have fixed behaviour when using “Test” and some other part of application - now correct error messages are shown.

    You can Test new per-release here:
    http://www.powerarchiver.com/test/release/powarc901.exe

    It will show proper error now (archive still doesnt work).

    thanks,

    Downloaded and installed on top of PA 9.01.01 (then rebooted).

    Test (shell extension) shows dialogue “Error in TAR/Gzip” twice !!
    Is this double/repeated dialogue correct (intended) ?
    Seems wrong (having to click OK twice)?
