Unzipping corrupted zip file

I have a corrupted zip file whose contents I'm trying to salvage. I know that the problem is with one of the files in the sbutman/taxes/ directory, and I've resigned myself to losing it. I've written the following short program to try to extract as much data as I can from the archive:
* Created on Sep 7, 2005
import java.io.*;
import java.util.zip.*;
* @author sbutman
public class ZipExtractor {
    static final int BUFFER = 8192;
    public static void main( String argv[] ) {
        try {
            BufferedOutputStream dest = null;
            FileInputStream fis = new FileInputStream( argv[0] );
            ZipInputStream zis = new ZipInputStream( new BufferedInputStream(
                    fis ) );
            ZipEntry entry;
            while( true ) {
                try {
                    entry = zis.getNextEntry( );
                    if ( entry == null ) break;
                    if ( entry.getName( ).startsWith( "sbutman/taxes/" ) )
                            continue;
                    System.out.println( "Extracting: " + entry.getName( ) );
                    if ( entry.isDirectory( ) ) {
                        File directoryEntry = new File( entry.getName( ) );
                        directoryEntry.mkdir( );
                    else {
                        int count;
                        byte data[] = new byte[BUFFER];
                        // write the files to the disk
                        FileOutputStream fos = new FileOutputStream( entry
                                .getName( ) );
                        dest = new BufferedOutputStream( fos, BUFFER );
                        while( ( count = zis.read( data, 0, BUFFER ) ) != -1 ) {
                            dest.write( data, 0, count );
                        dest.flush( );
                        dest.close( );
                catch( IOException ioe ) {
                    System.out.println( "An IO exception has occurred:" );
                    ioe.printStackTrace( );
                    continue;
            zis.close( );
        catch( Exception e ) {
            System.out.println( "A general exception occurred:" );
            e.printStackTrace( );
}When I run the program, everything works fine until I get to the zip file entry causing the problem. The output looks like this:
An IO exception has occurred:
java.util.zip.ZipException: invalid entry size (expected 4007 but got 4055 bytes)

        at ZipExtractor.main(ZipExtractor.java:23)The second error repeats itself until I ctrl-c out of the program.
What's happening is that the inner catch block detects the zip entry error as expected. It continues on the next pass through the while loop and attempts to read the next entry, whereupon the second IOException is thrown over and over again. (Incidentally, I've also tried using java.util.zip.ZipFile, but it won't even open the file.)
My questions are these:
1. What exactly does "Push back buffer is full" mean? I've looked through the javadocs, but my understanding is still sketchy. Can I manipulate the buffer or otherwise code around the problem in order to prevent this error from being thrown?
2. Is there any way I can see the source code for java.util.zip.ZipInputStream? It would be very helpful to see exactly where and why this error is being thrown.
Any help anyone can provide would be greatly appreciated. By the way, if this question should be better posted in another forum, let me know and I'll re-post it there.

No clue. Too few info.
Post a small demo code that is generally compilable, runnable and could reproduce your problem. See: http://homepage1.nifty.com/algafield/sscce.html and http://www.yoda.arachsys.com/java/newsgroups.html

"zip" Terminal command no help fixing corrupt zip file; any other workarounds?

I downloaded a ".zip" file containing some files that I need to access.
When I double-click on it, I get the "Unable to unarchive 'xyz.zip' into '[foldername].' ( Error 1 - Operation not permitted )" message, which many people report when they try to open a corrupt zip file.
I also tried opening the file with "StuffIt Expander," "Archive Utility," and "The Unarchiver," as well as some specialty zip-compression programs, but none were successful.
I then installed the very useful "Archive.qlgenerator" plugin (http://homepage.mac.com/xdd/software/archive/) which allowed me to at least see inside the zip file using OSX's "QuickLook" feature. Lo and behold, all the files that were supposed to be in the zip file are indeed in there, as they should be. The problem is not that the zip file is empty, the problem is that it has become corrupted somehow.
So, what I need to do is either "fix" the corrupted zip file, or alternately find some way to extract the needed files using brute force.
Following tips given on various forums, I tried using OSX's "zip" command in terminal (http://homepage.mac.com/kelleherk/iblog/C1901548470/E731143104/index.html and http://hintsforums.macworld.com/showthread.php?t=132146). I was able to use it properly, but unfortunately neither the "-F" nor the "-FF" commands were of any helping in "fixing" the zip file. The "-F" command incorrectly said that the zip file was empty and that there was nothing to fix; the stronger "-FF" command came back with
Could not find:
xzy.z01
Hit c      (change path to where this split file is)
    s      (skip this split)
    q      (abort archive - quit)
    e      (end this archive - no more splits)
    z      (look for .zip split - the last split)
or ENTER (try reading this split again):
...but none of the options produced any result. Pressing "z" gave me
Could not find or open
xyz.zip
...which means that even "-FF" could not get past whatever problem had corrupted the file.
So: is there any built-in way for Mac OSX to fix or extract the contents of a zip file corrupted like this?
Alternately, is there any third-party shareware or freeware that will do the trick?
(I don't want to have to spend big $$$ on a commercial program since all I need to do is open a single zip file. And there is no way to contact the zip file's original creator, so I can't download an uncorrupted version.)
Any help would be greatly appreciated.

Mark:
When I try your first suggestion in Terminal ("unzip -t /path/to/file"), I get this message:
Archive: /xyz.zip
End-of-central-directory signature not found. Either this file is not
a zipfile, or it constitutes one disk of a multi-part archive. In the
latter case the central directory and zipfile comment will be found on
the last disk(s) of this archive.
unzip: cannot find zipfile directory in one of /xyz.zip or
        /xyz.zip.zip, and cannot find /xyz.zip.ZIP, period.
When I try your second suggestion ("unzip -l /path/to/file"), I get the exact same error message. (And yes, I am fixing "/path/to/file" to be the correct path to the actual file).
And no, it is not really part of a multi-part archive. (Or at least it wasn't supposed to be; only one zip file is available, and there was only supposed to one.) Perhaps the zip was mis-encoded in the first place, so that the person who created it accidentally did something wrong which the unzip applications are interpreting as this file being part of a multi-part archive; but even so, all I have is this one file, so I need to fix it as is, or extract its contents as is, since I have no way to contact the original creator to do it right this time.

Problem in unzipping the zip files

Hi,
I have created a program to unzip the zip files. But when i try to zip it is creating the zipped files outside the folder where it is to be zipped.
what is wrong with my code.
if the zip file is migration.zip
if the path inside the zip file shows
and the path inside says this
/codebase/scripts/
it would create migration folder and create codebase folder outside the migration folder
what is wrong with my code

Problem in Unzipping the zip file

Hi
I have created a program to unzip the zip files in the folder named after the zip file
it is working well well when u try to zip zip files put in a directory
i.e u create a folder name contents and put files into that and then zip it
but when u directly create a zip file , without putting in a folder
it creates the folder and zip the files outside the folder
Another problem is that with the path
for e.g. suppose the zip file name is contents and path should show
contents/filename.txt but there are some other files whose path shows
res/file.txt. In this case it creates a folder of res and put it outside the
folder with the name of zip file
I have pasted my code :

Unzip a zipped file?

How can I unzip a zipped file with java ?

I presume you've read the API of [url http://java.sun.com/j2se/1.4.1/docs/api/java/util/zip/ZipFile.html]ZipFile?

Corrupted zip file of download pkg

I've tried downloading App server 7 (Platform edition) several times and from several download locations but each time I get corrupted zip file and can't open it. BTW, other stuff (Application framework, Studio 4, etc) is downloaded correctly. I'm using IE 6.
Has anyone experienced anything like this ?

No clue. Too few info.
Post a small demo code that is generally compilable, runnable and could reproduce your problem. See: http://homepage1.nifty.com/algafield/sscce.html and http://www.yoda.arachsys.com/java/newsgroups.html

Unzip a zip file

Can someone help me for the following problem,
Iam downloading a zip file from the server to the client.i want to unzip and execute the .EXE file, which is inside the zip file through the java coding.can any one help me!
thanking you

I think you can do all of this using the Java runtime interface which allows you to execute command line commands via Java code (ie, launching an EXE).
See http://java.sun.com/j2se/1.4.2/docs/api/java/lang/Runtime.html
I don't believe there is a component of the Java API that allows you to unzip a zip file. But you could still accomplish this using the winzip command line support. See http://www.winzip.com/wzcline.htm in combination with the Java runtime.

Corrupt ZIP files in Prod 11.1.2.1 - Workspace

Hello all,
This one has me and Oracle Support stumped.
Only Prod is exhibiting the following issue...
When exporting reports to a ZIP file, the file becomes corrupt, and gives an error when extracting with Windows. But what actually happens is that a file with the same name and NO extension (i.e. REPORTS) is in the REPORTS.ZIP file. This is what is causing the zip file to corrupt.
The workaround is to extract the file using 7-ZIP, rename the REPORTS file to REPORTS1.ZIP, save it, then unzip the REPORTS1.ZIP file.
This REPORTS1.ZIP has the reports that were zipped initially in Workspace.
Any ideas what may be causing this? No other environment has this issue.
Thanks in advance!!

ZIP file seems to be corrupted. You must repair the file first. Do repair the file by using WinRAR program.
Open WinRAR *>* open ZIP file *>* go to Tools *>* select Repair archive *>* Browse the path *>* check the box Treat the corrupt archive as ZIP *>* click on OK *>* wait for a while once the selected file is repaired *>* click on Close.
Or if this solution fails to repair the file, then you must take help of third-party ZIP recovery software. A wide range of ZIP recovery software are available on the internet. Check few of them. You can use their demo version first. I can recommend you SysInfoTools ZIP Recovery software. You must try its free demo version before buying any other ZIP recovery software.
Regards.

Want to partly unzip a zip file

I'm trying to upgrade a BIllion 7404 gateway. The relevant firmware is at the top of the list here:
http://au.billion.com/support/bipac7404vgpm.php
If my understanding is correct the zip file for the firmware upgrade contains a file within it, a .afw file, that will upgrade the firmware on the Billion. However, when I double click on the zip file, Stuffit unzips the whole lot and I end up with 29 separate files that make up the .afw file, whereas I need the .afw file intact.
If I put the zip file, call it Upgrade.zip, onto a disk called G5-Data (the name I have given the internal drive on my G5), and use the Terminal command unzip, can anyone tell me the exact command I would need to type in to get a hold of the unzipped .afw file that resides within the zip file?
Thanks in advance for an suggestions.

Hi Cole,
I don't really understand how I got the file, but I got it. The file that I wanted itself contains 29 files that you are not supposed to see. When it is unzipped on a PC, the unzip process stops at the first layer, and that file is recognizable by the gateway as a firmware upgrade file. But if you give the gateway the folder with the 29 files it doesn't know what it is.
Stuffit reaches into the second layer and unpacks the lot into a folder of 29 files. Must be something in the zip file that is incorrectly setup that allows Stuffit to do that.
Anyway, I tried the command I posted and up came one file. I found a program called BetterZip that also unzips the file correctly. Maybe there is something wrong with Stuffit 10 and I should give it the boot. Do you know anything about that?
Thanks again for your help,
Guy

I've written a replacement zip file creator class. Not much tested but it seems to work, however I've yet to try it with the version of WINZIP that rejected my previous attempts. Oh, and the stored dates are garbage.

* probably because they use

* a file is writen to a special block following the data. Since the length of the binary
* date is unknown this makes an archive quite complicated to read, and it looks like
* WinZip hasn't bothered.
* All data is Deflated. Close completes the archive, flush terminates the current entry.

Cannot unzip 10g zip file

Hi,
I tried to download the 10g zip file for windows but when I try to unzip it I get the message that the zipfile is not a valid archive. I then tried to download the separate components, but with the same result.
I'm using winzip 8.1
Cheers,
Magnus

Hi,
It seems like if the partition where the TEMP folder is located isn't big enough, the download fails. The downloaded file becomes the size of available space for TEMP.
The strange thing is that the download says 576 Mb (or something), and there is no error, but the file becomes only 270 Mb (in my case).
After allocating more room for TEMP the download worked fine.
Cheers,
Magnus

How to unzip and zip files

I have a very large number of Karaoke music that plays on my windows pc but some will not play on my Mac. I think i need to unzip & re-zip them to play on my mac but i'm not sure exactly how to do this. any suggestions? Do I need a special program? running os x 10.9.3

Zip files can be opened with the built in 'Archive Utility' application. Double click any zip file & it will try to unzip it.
This application is tucked away inside /System/Library/CoreServices/Archive Utility. If you want to set preferences for it you need to open the location in Finder by using the 'Go Menu > Go to Folder…', enter /System/Library/CoreServices/ for the path & then open the Archive Utility application and look in it's preferences.
I expect that zipping & rezipping will not do anything useful for you. I suspect that the file format is the issue.
Unzip some files & post what the Finders 'File > Get info' panel shows, take a screenshot of it with 'cmd+shift+4', then drag the crosshairs to select the area. it will appear on the Desktop for uploading here.
You may need to find a compatible player or find a way to convert them if the Mac cannot play them.
P.S. to zip a file(s) select the items & right click, select 'Compress x items' & you will get a zip archive - I don't think it will help you though
