How to compress or zip excluding '.DS_Store' files

I have to create a zip file in order to upload multiple files to a specific application. Unfortunately, it rejects the zip created on a Mac because it contains
hidden files. Any solutions besides going to Parallels everytime I need to do this. It would be much appreciated.

Found this:
http://bechster.com/zip-a-folder-on-mac-osx-without-the-pesky-ds_store-files/
I've not tried it myself.
The other way would be to make the invisible files visible and remove them first, then zip.

How to permanently stop creation of .DS_Store files on desktop?

Ever since attempting to use .ds_store on Terminal to find hidden iTunes files, the system will not stop creating .DS_Store files on the desktop. I've tried using the defaults write com.apple.desktopservices DSDontWriteNetworkStores true command, to no avail. I'm relatively new to using Terminal, so if someone could offer any tips, that would be good. The file creation is more of an annoyance than a real problem, but I want to know how to stop it, since there is no info on this in other places. Thanks! ~ Eva

The DSDontWriteNetworkStores command only prevents creation on shared network drives.
.DS_Store files are always created locally (unless using something like TotalFinder to prevent that)
The reason you now see them on the Desktop is likely because during the process to track down iTunes files you enabled the option to "see" hidden files - issue the following command in Terminal to "undo" that:
defaults write com.apple.finder AppleShowAllFiles false
If you want the change to be immediate (rather than after logging out & back in or rebooting) then simply "restart" the Finder app, again in Terminal:
killall Finder

How do I create a new .DS_Store file for the Desktop?

I have an account, in this case it is the System Administrator account (which I seldom use), where the Desktop icons all scrunch up to the right side of the screen. I can re-arrange them, but when I log out and sign back on, the icons are shifted back to the right side of the screen. I thought perhaps I had a corrupted .DS_Store file that needed to be removed. However, it turns out that I can find no .DS_Store file to remove for this account. Finder just doesn't seem to be able to create a new one. I'm not sure how or when the old one disappeared.
Any suggestions how I can get the Finder or something else to create a new .DS_Store for the Desktop so that icons will stay put?

I think I found an answer (not a solution) to my problem. Consulting with Apple Support, there is no way for the System Administrator's desktop to "remember" the positions of icons from one session to the next. They will always move to the right-hand side of the screen when you log back in. Apparently this is a change that occurred with OS 10.6.4. No reason by Apple given for the change, nor is it readily apparent to me why the Desktop or Finder in the System Admin account should work any differently than in any other account. Might simply be an oversight or a bug.
If anybody has a fix, I would appreciate learning about it.

How to compress a bunch of .java files into a single .jar file?

Hello everyone! I am working on a Chinese segmentation job. Someone offers very excellent
such tool. When I copy his example, I find it imports
          import org.apache.lucene.analysis.Analyzer;
          import org.apache.lucene.analysis.Token;
          import org.apache.lucene.analysis.TokenStream;
          import org.mira.lucene.analysis.IK_CAnalyzer;I have downloaded IK_CAnalyzer.jar file which contains org.mira.lucene.analysis.IK_CAnalyzer class.
I find that I need to download lucene, thus I went into the following website
http://lucene.apache.org/#06+May+2008+-+Lucene+Java+2.3.2+availableand downloaded the lucene-2.3.2-src.tar.gz. Aftre unzip, I found all java source files in java directory (and in many other different subdirectories). Now it seems I need to compile all the src files and compress them into a single .jar file while keeping their original hierarchy unchanged
I think I should use jar command and with some additional options.
Can anyone show me how to do that?
Many thanks!

Thanks for reply, I?ve read that tutorial before I post. Howevver, it do tells how to compress a jar file.
The question I have is how to compile two .java file stored in different packages like
rootPackage-->subPackage-->a.java
rootPackage-->subPackage2-->b.java
I want to compile a,java and b.java both and keep their hierarchy like rootPackage.subPackage.a unchanged. If I directly go into subPackage and compile a.java, I think the hierarchy is changed.
What do you think about it?

How to compress and decompress a pdf file in java

I have a PDF file ,
what i want to do is I need a lossless compression technique to compress and decompress that file,
Please help me to do so,
I am always worried about this topic

Here is a simple program that does the compression bit.
static void compressFile(String compressedFilePath, String filePathTobeCompressed)
          try
               ZipOutputStream zipOutputStream = new ZipOutputStream(new FileOutputStream(compressedFilePath));
               File file = new File(filePathTobeCompressed);
               int iSize = (int) file.length();
               byte[] readBuffer = new byte[iSize];
               int bytesIn = 0;
               FileInputStream fileInputStream = new FileInputStream(file);
               ZipEntry zipEntry = new ZipEntry(file.getPath());
               zipOutputStream.putNextEntry(zipEntry);
               while((bytesIn = (fileInputStream.read(readBuffer))) != -1)
                    zipOutputStream.write(readBuffer, 0, bytesIn);
               fileInputStream.close();
               zipOutputStream.close();
          catch (FileNotFoundException e)
          catch (IOException e)
               // TODO Auto-generated catch block
               e.printStackTrace();
     }

I am a PC user - bought my 1st Mac today. Was trying to download a VLC player for my movies but i can't open files when i download them. I tried downloading winc=ace - but it came in an exe file as well and it just opens as a word file of computer language. I tried loking on the net - not much help - something about mounting a file - but there is no file mounter. Please help getting very frustrated. I guess i know how people who have never used a computer before feel like....
Thanks for your help

You need MacUnace from the Winace site

How do I compress a string with java.util.zip - not a file ?

How do I compress a string with java.util.zip?
Is possible to compress something else except a file?

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.

How do you use zip files?

Hello all,
I have always stayed away from ZIP files (as in doing it myself, to my own files), since my days in Windows, after all the countless corrupt ZIP files I received from others, that simply would not UNzip...
But recently I've come across references to them again, and I realised I might be missing a trick or two....
Any comments on the following would be appreciated:
1.) What can I use them for?
As in - could I ZIP my entire folder of holiday pictures - all 13GB's of them?
Or is there some sort of size limit, where anything over, and things become problematic?
Are some file types Zipped better than others?
2.) How does it actually work?
As in - what happens to my original files?
Assume the holiday pics are Zipped - do the orginals get compressed, or can I select it so that copies are Zipped, as a kind of backup?
3.) How safe is it?
As in - assuming my hardware and software are all OK, nothing buggy etc. - if I create the ZIP file, pop it somewhere on a USB/External/the same laptop, and then Unzip it later, when I need them again - am I correct in assuming that the chances of the file being corrupted, are relatively slim?
And coming back to those holiday pics - could the compression process result in a loss in picture quality/resolution, were I to then unzip the file? Or - assuming everything works as planned - will the quality of the pictures/file emerge exactly the same as they were prior to being compressed?
I realise all of the above are ridiculously simple questions - but googling this doesn't really help, as most sites simply explain the how to, not the WHY...
The WHY articles were probably all written 15 years ago already... I'm just very, very far behind....
Thanks in advance!

Zipping an image file should have no effect on image quality, as the image data is not actually changed.
Note that there's very little point in zipping a folder full of images, unless the images are not a compressed file type. You can't compress data that is already compressed - in fact, trying to do so often increases the file size - and JPEG images, for example, are already compressed.
For the most part, you don't need to use zip at all. I absolutely DO NOT recommend storing your files and/or folders on the hard drive in compressed form as a space-saving measure. It doesn't save enough space to be worth the time needed to compress files large enough to warrant it on a modern drive. Accessing zipped files is a pain, too, since you basically have to decompress the whole thing in order to access a file inside a zip file.
Zip becomes useful if you need to attach a large number of files to an e-mail message (zip the files, then attach the single zip file) or want to create an archive of multiple files to download from a web site through a single link. In other words, in situations where you need to transmit many files over the internet, especially where Windows users may be involved, zipping files can be either important or a convenience.

How to compress large files

Can anyone tell me whether os x has any good built in compression utilities? Or where to download some free ones?? I've got some rather large DV project folders that i want to compress onto one DVD and then delete them off my hard drive.
Also how do you compress file to .mpkg? That's the extension of a compressed file from an apple utility that i found. once it was opened turned out to be 1.8 gig from 456k.

OSX can create a .zip archive.
Select the folder in the Finder, and goto the File menu and select Create Archive.
But I'm not sure how high compression rate you can gain for your DV project.

How can I zip a music file?

hello,
I am very new with mac, I would like some help in how to compress a music file as well as what type of extention will I need?
thank you

Hi,
Welcome to the Apple Discussions.
Probably the easiest way would be to select the file in the Finder, then use the "Create Archive of (song file name)" menu item from the "File" menu. It'll compress it and add the file extension automatically.
So, to compress a file you've selected in iTunes, you'd choose "Show Song File" from the iTunes "File" menu. A window will pop to the front with the song file highlighted. Now you're using the Finder application. Its "File" menu has the "Create Archive of (song file name)". Select that and you should get a zipped archive of your song.
Be aware, though, that if you are compressing an MP3 or AAC compressed file, it's not likely to get very much smaller, if at all. In general, files that are already compressed don't compress very much more. And the more they're compressed in the first place, the less they'll compress using a second method.

How to compress a pdf file without quality loss

How to compress a pdf file without quality loss? Please help....

With the way you worded the question, your only option is to zip (or equivalent) the PDF. There are options in terms of graphic compression (this is generally a loss of quality in reducing the pixels) and nonstorage of fonts (likely making the file unreadable to some). So there are techniques, but with a tradeoff. It all depends on what you mean by loss of quality.
The other techniques that do not lose quality, but give up on some functionality are to remove links, bookmarks, and tags. The tags are often necessary only for converting a PDF back to another form and maintaining accessibility - important in some business situations. These are all tradeoffs that give something up.

How can I keep lion from generating .DS_Store files on windows network partitions, but not disable it for all network partitions?

How can I keep lion from generating .DS_Store files on windows network partitions, but not disable it for all network partitions? I am fimilar with changing the setting for all network partitions(defaults write com.apple.desktopservices DSDontWriteNetworkStores true), but that is undesirable when I connect my laptop to my home network. A preferable solution would be where I could control the writing of these files based on disk format (NTFS vs HFS+).

Go to MacUpdate or CNET Downloads and search for ds_store. There are numerous utilities for preventing them from being transferred to Windows systems.
