Using java.util.zip.ZipFile

I have files that are about 4GB (with possible growth in the future) that will be sent to a file system and a java process will be used to unzip them.
Is there a size limit for unzipping files using java.util.zip.ZipFile?

Hi annie613,
Indeed, there's a size limit of 2GB for unzipping files, more precisely when the size of the inflated file reaches 2GB !
Edit : inflated instead of deflated
Edited by: Chicon on Jun 29, 2009 3:56 PMHmm, this blog says that the current limit of 4GB has been expanded by implementing ZIP64 support in OpenJDK7 build(b55).

How do I estimate time takes to Zip/Unzip using java.util.zip ?

If I am compressing files or uncompressing zips using java.util.zip is there a way for me to tell the user how long it should take or for perhaps displaying a progress monitor ?

For unzip use the ZipInputStream and pass it a CountingInputStream that keeps track ofr the number of bytes read from it (you write this). This CountingInputStream extends fileInputStream and as such can provide you with information about the total number of bytes available to be read and the number already read. This can give a crude idea of how much work has been done and how much work still needs to be done. It is inaccurate but should be good enoough for a progress bar
As for zipping use the ZipOutputStream and pass it blocks of information. Keep track of the number of blocks you have written and the number you still need to write.

Java.util.zip.ZipFile.entries() shows only 99 files but zip file is fine.

Hi,
I have a wierd issue with java.util.zip.ZipFile
Code as simple as
ZipFile file = new ZipFile("my.zip") ;
System.out.println(file.size());
For this particular zip file, it says 99 files found but the zip contains more than 60,000 files. I tried the zip with unzip and zip utilities and the zip file checks out fine. I even tried to unzip the contents, and zip 'em up all over again, just to eliminate the chances of corruption while the zip was being transferred over the network.
The same program works fine with another zip containing more or less the same number of files and prints 63730.
Any idea? This can not possibly be related to the type of files the zips contain? right? In any case, the contents of both zips are text/xml files.
Any help would be greatly appreciated.

I know its a problem with this particular zip. But whats interesting is that "unzip" can easily open / verify the zip and claims that it is a valid zip.
As I wrote earlier, I unzipped the file and zipped up the contents again in a new zip but java can't still count the contents correctly.
So I am thinking there is something to do with the "contents" of the xmls inside the zip? (characterset issues?)
There are no exceptions thrown and no error anywhere :(
I basically need to pinpoint the issue so that I can have it corrected upstream as this zip file processing is an ongoing process and I need to resolve it not just once but for the periodic executions.
Hope this helps explain the issue.

does any body has the java code for
zipping files in a folder
hi guys,
actually i want to zip no of files in a folder .the folder can also have sub folder
and after zipping when i extract the files manually i should
maintain the same folder structure
does any body has the code
please reply me soon its a bit urgent

hi smeee
i tried running ur code but its not working
here the command
java c:\abc\ zzz.zip
its saying
no files or directories even though there's the
directory present
what's the solution Hi,
Oops that was because of the error check added at the last moment..
Anyway, You need to use the following command to run it :
java ZipUtility c:\abc c:\zzz.zip
Please use the following corrected code:
     Class to zip file(s).
     Requires jdk1.3.1.

Problem in deleting Zip files unzipped using java.util.zip

I have a static methos for unzipping a zip file. after unzipping the file when i am trying to delete that file using File.delete()its not getting deleted. but when methods like exist(). canRead(), canWrite() methods are returning true what can be the possible problem ? i had closed all the streams after unzipping operation Please go through the following code.
public static boolean unzipZipFile(String dir_name, String zipFileName) {
try {
ZipFile zip = new ZipFile(zipFileName);
Enumeration entries = zip.entries();
while (entries.hasMoreElements()) {
ZipEntry entry = (ZipEntry) entries.nextElement();
// got all the zip entries here
// now has to process all the files
// first all directories
// then all the files
if (entry.isDirectory()) {
// now the directories are created
File buf=new File(dir_name,entry.getName());
buf.mkdirs();
continue;
}// now got the dirs so process the files
entries = zip.entries();
while(entries.hasMoreElements()) {
// now to process the files
ZipEntry entry = (ZipEntry) entries.nextElement();
if (!entry.isDirectory()){
File buf=new File(dir_name,entry.getName());
copyInputStream(
zip.getInputStream(entry),
new BufferedOutputStream(
new FileOutputStream(buf)));}
} catch (IOException e) {
e.printStackTrace();
return false;
return true;
now i am trying to call this method to unzip a zip file
public static void main (String arg[]){
unzipZipFile("C:/temp","C:/tmp.zip");
java.io.File filer = new File("C:/tmp.zip");
System.out.println (filer.canRead());
System.out.println (filer.canWrite());
System.out.println (filer.delete());
Please tell me where my program is going wrong ?

Thanks .. the problem is solved... i was not closing the Zip file .. rather i was trying to close all the other streams that i used for IO operaion ... thanks a lot

Java.util.zip.ZipFile is not thread-safe?

I didn't find any notes in its javadoc.
Actually I want to know whether ZipFile.getInputStream(ZipEntry) method is thread-safe. As I mentioned there is no information in the javadoc but I suppose that ZipFile is not thread-safe.
Am I right?

More classes are safe if you don't attempt to change
anything. However if you change the ZIP file while
attempting to read it, forget it.I doubt that you can read any 'file' without 'changing' something.
Low level file io almost always uses buffers. I am not even sure if modern operating systems allow byte access to files on the hard drive anymore. And buffers are modified when they are read.

Java.util.zip.ZipException Error

I created a jar file, and put in C:\tools
C:\tools>java -jar myjar.jar is working fine
However, if I try to run myjar.jar in other directories, then I have problems.
I already set the classpath:
SET CLASSPATH=.;%CLASSPATH%;C:\tools\myjar.jar;
Here's the error. Any ideas???
C:\>java -jar myjar.jar
Exception in thread "main" java.util.zip.ZipException: The system cannot find th
e file specified

at java.util.jar.JarFile.<init>(JarFile.java:117)
at java.util.jar.JarFile.<init>(JarFile.java:55)

You always need to specify a proper file name when you use the -jar switch. If you are not in c:\tools you have to run with "java -jar c:\tools\myjar.jar".
Setting the classpath in particular doesn't help becuase the file name given to the -jar switch will override all settings for classpath. http://java.sun.com/j2se/1.4/docs/tooldocs/findingclasses.html#userclass
But since you now have myjar.jar in your classpath, you can run the application from any directory with "java your.main.ClassName" :)

from my experience, using weblogic jars can be a pain if the full install is not on the local box.
Note that you dont have to 'install' it. Just copy the directory.
Reason is that the jar files have manifests with relative classpaths.
For an example of horror take a look at the weblogic.jar MANIFEST's classpath entry.

Java.util.zip not handling Unicode filenames

I have a zip file that contains files with Asian filenames. java.util.zip.ZipFile opens it, but the filenames are garbled. Is there any way to handle filenames that contain unicode characters?

Of course, compression works on bytes, not some higher level constructs like Strings or files.
You can use the ZipOutputStream or DeflaterOutputStream for compression.
And the javadoc for Deflater even has a code example of compressing a String.

Running JAR gives me java.util.zip.ZipException

I just made a JAR--we'll call it MyApp.jar--containing some classes in the JAR's main directory (that is, not in any subfolder, just in the top level), and the following manifest that I put in from a text file i called "MANIFEST.MF":
"Main-Class: MyApp (i also tried using "MyApp.class")
Class-Path: smartjcommon_1.6.jar smartjprint_1.5.6.jar smartjprint_demo.jar
Those JARs in the class-path are three JAR files in the same directory as MyApp.jar that are used as external libraries for my program. I go to the command prompt, go to the directory with these JARs, and type in:
java -jar MyApp (i also tried adding -window at the end, as I've seen done, since it's a Swing program)
and I get:
Exception in thread "main" java.util.zip.ZipException: The system cannot find the file specified
at java.util.zip.ZipFile.open(Native Method)
etc etc
I'm sure it's a very simple problem, but what am I doing wrong?

You aren't spelling the name of the jar file correctly. Tryjava -jar MyApp.jarinstead.

I have seen problems like this in the past. When you create your war file, try using "jar
          cv0f" so that the jar file won't be compressed...

Extracting file from a TAR file with java.util.zip.* classes

Is there a way to extract files from a .TAR file using the java.util.zip.* classes?
I tried in some ways but I get the following error:
java.util.zip.ZipException: error in opening zip file
at java.util.zip.ZipFile.<init>(ZipFile.java127)
at java.util.zip.ZipFile.<init>(ZipFile.java92)
Thank you
Giuseppe

download the tar.jar from the above link and use the sample program below
import com.ice.tar.*;
import java.util.zip.GZIPInputStream;
import java.io.*;
public class untarFiles
     public static void main(String args[]){
          try{
          untar("c:/split/20040826172459.tar.gz",new File("c:/split/"));
          }catch(Exception e){
               e.printStackTrace();
               System.out.println(e.getMessage());
     private static void untar(String tarFileName, File dest)throws IOException{
          //assuming the file you pass in is not a dir
          dest.mkdir();
          //create tar input stream from a .tar.gz file
          TarInputStream tin = new TarInputStream( new GZIPInputStream( new FileInputStream(new File(tarFileName))));
          //get the first entry in the archive
          TarEntry tarEntry = tin.getNextEntry();
          while (tarEntry != null){//create a file with the same name as the tarEntry
               File destPath = new File(
               dest.toString() + File.separatorChar + tarEntry.getName());
               if(tarEntry.isDirectory()){
                    destPath.mkdir();
               }else {
                    FileOutputStream fout = new FileOutputStream(destPath);
                    tin.copyEntryContents(fout);
                    fout.close();
               tarEntry = tin.getNextEntry();
          tin.close();
}
