Zip-Unzip

New to Mac. Is there a file compressor/decompressor that comes with OS X? If not, any recommendations for an open source/freeware/shareware or inexpensive version? I need to compress as well as decompress.
Thanks,

Thanks, Duo. New to Mac, but I always get a quick response here.
The file I was working with was an extension for Thunderbird. When I did the double-click/right/click thing on it, I was given the option of "Compress." I expected "Uncompress," but I said, "Oh, what the ****." Sure enough, I got a zipped file. With it I got an "Uncompress/Unzip" option, which gave me what I wanted. The original file unzipped. I don't understand the logic, but it worked.
Cool that Mac has zipping/unzipping built-in. Of course, since it makes sense.
Thanks again,

Zip/unzip problem

I have a problem unzipping Objects that i've zipped earlier.
The situation is as follows:
a RMI server zips a tree of Objects. The client side of the program tries to unzip the data and form it back to the Object (a DefaultMutableTreeNode) that is should be. However...
The zip part goes without any problems. The unzipping however gives me a StreamCorruptedException.
I have an object called ZipObject and it contains the size (int) of the zipped data and the size (int) of the uncompressed data. It also holds the data itself.
my zip/unzip methods are as can be seen at:
http://www.next-element.nl/~orchid/zip.html
if anyone can help me...i'd be very grateful.
thanx in advance.

Oh yes i checked the ingoing and outgoing size of bytes...
they are perfectly the same.
The problem lies more in the in.readObject() method.
when i dump the bytes that i receive to a File (which i do not want to do in the application) i can actually unzip it with unzip from my Linux system! But in my app. i don't write the objects to file...i just need the object back. but the data comes in clean.

Zip/unzip desing and configuration

Hi,
I need to implement zip/unzip file to file scenario . can u help me complete design and configuration steps .I mean how to deploy java code. and designing in IR and how to configure in ID.
thanq

Hi,
You Do not need to Provide any JAVA Code For the same.
SAP Provides Standard Modeules to DO so.
Use the PaYLoadZipBean module.
Have a look at the SAP help link:
[http://help.sap.com/saphelp_nw70/helpdata/en/45/da9358a1772e97e10000000a155369/frameset.htm]
just a Few Points to remember:
1. Place this Before the call to Standard SAP module in case you want to Unzip the payload in the Sender Side
2. Place it after the SAP Standard module in the receiver side.
Hope this helps.
Reward points if useful

Zip/unzip API for both Windows/Linux

hello, there:
I wonder if it's possible that we can create a zip/unzip class that can package the files in Windows and unzip them in Linux?
Fact is, that I created a Swing application, which shows a tree of a certain folder. Upon request, the app also zip that folder(including it's subs) and upload it to a remote database as a SQL blob. Well, I want this app to work on both Windows/Linux, meaning when it runs on Linux, it should be able to download the package and unzip the package to its full extend.
But it looks like that the files zipped in one OS can't be easily unzipped to its original in another. Is it doable or not possible due to the very different nature of the file systems of different platform?
I used a open source code from this link, http://www.wakhok.ac.jp/~tatsuo/sen97/10shuu/UnZip.java.html
Will the zip package from jdk help (java.util.zip)? I haven't tried that one yet.
Thanks,
Sway

You don't have to use special libraries as the tools you need are all in the java.util package.
There is however an Apache Commons library for this though which you can find here
http://commons.apache.org/sandbox/compress/
Note that zip = archiving and compression where as gz or gzip on Linux is only compression and you would use tar to do the archiving (tar.gz), that's why there are two separate compression classes in the Java API.

File-roller should have zip/unzip depedency

I have gnome installed and tried to open a zip file using file-roller. It did not work because the zip and unzip packages were not dependencies. The ubiquitous nature of the zip standard should make it a dependency on any file compression utility like file-roller. Just my humble opinion.

I don't agree. Zip is not very common in linux. File-roller can handle it, if zip / unzip is installed, but literaly it does not really "depend" on it. For my taste, it is clear and simple: If you need another additional compression utility, next to the commonly used and installed (tar) you may install it (zip, unzip, bzip, ...). It should'nt just because you decide to use file-roller. Keep it simple does not mean install everything a user might want, as f.e. ubuntu would do.

Recommended zip/unzip utility

Can someone recommend a good zip/unzip program for the Mac – one that will allow me to unzip password-protected (encrypted) zipfiles that were originally created on a PC?
(One that’s freeware would be particularly welcome.)
Thanks.

I have no idea what going on. Did you launch the Terminal.app in /Applications/Utilities/? If so, if you type the following in the window that pops up and hit the return key:
unzip
you should get:
$ unzip
UnZip 5.52 of 28 February 2005, by Info-ZIP. Maintained by C. Spieler. Send
bug reports using http://www.info-zip.org/zip-bug.html; see README for details.
Usage: unzip [-Z] [-opts[modifiers]] file[.zip] [list] [-x xlist] [-d exdir]
Default action is to extract files in list, except those in xlist, to exdir;
file[.zip] may be a wildcard. -Z => ZipInfo mode ("unzip -Z" for usage).
-p extract files to pipe, no messages -l list files (short format)
-f freshen existing files, create none -t test compressed archive data
-u update files, create if necessary -z display archive comment
-x exclude files that follow (in xlist) -d extract files into exdir
modifiers: -q quiet mode (-qq => quieter)
-n never overwrite existing files -a auto-convert any text files
-o overwrite files WITHOUT prompting -aa treat ALL files as text
-j junk paths (do not make directories) -v be verbose/print version info
-C match filenames case-insensitively -L make (some) names lowercase
-X restore UID/GID info -V retain VMS version numbers
-K keep setuid/setgid/tacky permissions -M pipe through "more" pager
Examples (see unzip.txt for more info):
unzip data1 -x joe => extract all files except joe from zipfile data1.zip
unzip -p foo | more => send contents of foo.zip via pipe into program more
unzip -fo foo ReadMe => quietly replace existing ReadMe if archive file newer
That's the short version. For the long version, type in the following and hit the return key:
man unzip
If you didn't type these in the Terminal.app window, I have no idea what you're doing.

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.

Problem with zip/unzip of .swf files in XP

For some reason, zipping a .swf file in XP and then unzipping on another XP machine, the file suffix changes from ".swf" to no suffix and properties change from Flash movie to Flash object. Consequently, linking to the file with a URL in a presentation causes the file not found error. Renaming the unzipped file to filename.swf makes it unreadable.
Any suggestions on how to compact .swf files without them being corrupted when they're unzipped?

Sorry to say, aknle, I use Illustrator files in every After Effects project I do these days. I have never had the issue you are describing. I often receive files form external artists that I need to change to RGB from their CMYK originals. I often need to fix their art because they are print people and think of white as the paper and the absence of ink. But the files open and track and update for me flawlessly. Always have.
I am on CS5 (not 5.5) using a Macintosh.

Zip,unzip format files supported by XI

Dear all,
I have two requirements
1)1 have a huge pdf files(total 15) each of size 10mb these files need to be zipped in the sender CC ,set to XI and un zipped at the receiver ie I need 15omb pdf files at the receiver.The idea is to reduce burden on XI.
2)A huge Xml(400mb) file is split in to multiples of 10 these files must be zipped individually in xi and send the unzipped file to the receiver.
Thanks.

Zip/Unzip RoboHelp files

Need instructions on how to zip and unzip roboehelp 6 files.
When I zip, try to send file attachment, then try to unzip all I
view is long stream of files and open up RH xpj but see nothing but
empty new robohelp file.

I get the empty RH shell when I open the xpj from within the
zip file.
Depending on the zip program you use, the zip folder may look
almost exactly the same as a regular folder. So perhaps you are
opening the xpj that is in the zip file, rather than the extracted
one?
Perhaps try the following:
* put the zip file in c:\temp
* extract to c:\mytestproject (or something else completely
different from the location of the zip file)
* make sure you navigate to c:\mytestproject to open the xpj.

Does SL have a built-in zip/unzip utility?

I was wondering if I can unzip zipped files in SL or if I will need to purchase a utility like Stuffit?

Yep, it sure does.
From the help menu:
To compress items:
Do any of the following:
Select the item or items you want to compress and choose File > Compress.
Control-click an item and choose Compress from the shortcut menu.
In a Finder window, select one or more items and choose Compress from the Action menu (looks like a gear).
If you compress a single item, the compressed file has the name of the original item with the .zip extension. If you compress multiple items at once, the compressed file is called Archive.zip.
To uncompress (expand) an item:
Double-click the .zip file.
Basically you can just right click (control click) on a folder or group of files and compress them. To uncompress just a simple double click will do it.
Hope that helps

Free java library to zip/unzip files

Hi all,
I would like to know if there is any java library to zip and unzip files that can be used freely.
Thanks in advance,
Miguel

Thanks for your answer but what I am looking for is a java class library (and not a java zip utility) similar to the one developed by Chilkat (http://www.chilkatsoft.com/refdoc/javaCkZipRef.html) but I need it to be freely distributable. Obviously, I tried to find it with google before posting in this forum, but I didn't find anything.

I believe (although I don't want to put words in his mouth) that Madan has run across a similar problem that I am trying to solve.
For instance if I have the following files:
c:\pic1.gif
c:\pic2.gif
c:\pic3.gifand I zip them in to a file called: pics.zip the will unzip just fine.
However, if I have them in a directory:
c:\pics\pic1.gif
c:\pics\pic2.gif
c:\pics\pic3.gifA listing of the zip files (all using java of-course) will show the files and dirs correctly:
\pics\pic1.gif
\pics\pic2.gif
\pics\pic3.gifbut will give the following error if you try to un-zip them:
"The system cannot find the path specified"The ZipEntry class has an 'isDirectory()' method, but it only returns true in the case of an EMPTY directory. If , as in my example, there is an actual file at the end of the entry, it returns false.
So, at least in my case, I would be looking for advice on how to expand files that reside in directories within the zip file.
Thank You for any help you can provide
