EDIT, after many downvotes: I was using this option for some time ago and I don't know where I learnt it, so I can't give you a better explanation. Chris Johnson's answer is correct, but I won't delete mine. As one comment says, it's more accurate to what OP is asking, as it compress without those files, instead of removing them from a compressed file. I find it easier to remember, too.
The top level file of a zip archive with multiple files should usually be a single directory, because if it is not, some unarchiving utilites (like unzip and 7z, but not Archive Utility, The Unarchiver, unar, or dtrx) do not create a containing directory for the files when the archive is extracted, which often makes the files difficult to find, and if multiple archives like that are extracted at the same time, it can be difficult to tell which files belong to which archive.
Archive Utility only creates a __MACOSX directory when you create an archive where at least one file contains metadata such as extended attributes, file flags, or a resource fork. The __MACOSX directory contains AppleDouble files whose filename starts with ._ that are used to store OS X-specific metadata. The zip command line utility discards metadata such as extended attributes, file flags, and resource forks, which also means that metadata such as tags is lost, and that aliases stop working, because the information in an alias file is stored in a resource fork.
Normally you can just discard the OS X-specific metadata, but to see what metadata files contain, you can use xattr -l. xattr also includes resource forks and file flags, because even though they are not actually stored as extended attributes, they can be accessed through the extended attributes interface. Both Archive Utility and the zip command line utility discard ACLs.
The other tool, and maybe the one that the Finder actually uses under the hood, is ditto. With the -c -k options, it creates zip archives. With this tool, you can experiment with --norsrc, --noextattr, --noqtn, --noacl and/or simply leave off the --sequesterRsrc option (which, according to the man page, may be responsible for the __MACOSX subdirectory). Although, perhaps the absence of --sequesterRsrc simply means to use AppleDouble format, which would create ._ files all over the place instead of one __MACOSX directory.
Opening zip files is even easier, all you need to do is just double-click on the archive and it will expand automatically with Archive Utility in the same folder the archive is stored in.
That is for 10mb files like: smallzips.zip smallzips.z01 smallzips.z02But you could use another compression to make smaller file instead. Look at tar gzip bzip etc. 1 file is always better that 2.
Whatever your use case, the good news is that there's no need to download additional software to compress files in macOS. That's because Apple includes a built-in ability to zip files on your Mac, allowing you to quickly compress single files, groups of files, or entire folders. Keep reading to learn how.
If you compressed a single file, the zip archive takes the same name and adds a zip extension. If you compressed more than one file or folder, the zip archive will be named "Archive.zip" by default.
Apple hides the Archive Utility because it's a core service of the operating system. While this utility is tucked away, Apple makes zipping and unzipping files and folders extremely easy by selecting them in the Finder.
Usually, you use the Archive Utility without launching it. However, if you have a large number of files to compress or decompress, you should launch the utility and drag and drop files and folders on it. The Archive Utility is located at System > Library > CoreServices > Applications.
Zipping files on Apple/Mac is a chore because of all the hidden files and folders added by macOS. Like .DS_Store and __MACOSX are two of the most common files and folders that are added to zip files when compressed on macOS.
The folder named __MACOSX especially is problematic because it contains duplicates of every file in the zip archive. So for example, if you use Finder to compress 20 files, the resulting zip file will contain the original 20 files, plus an additional 20 files all hidden under the /__MACOSX/ folder.
Here are some screenshots showing the hidden files and folders that are included for any folder compressed (zipped) on macOS. First screenshot shows the hidden __MACOSX directory, which is visible on PC when you open the zip file.
The next screenshot shows the set of duplicate files and folders that are included in zip files compressed on macOS. Notice the file names, each begin with a dot ., which makes the files hidden by default on most systems.
So again, all the hidden files/folders added by Mac are included in the unzipped files ONLY when the files are unzipped on non-Mac machines. Thus the confusion: Why on earth are the hidden files added in the first place? They are completely excluded when unzipping on Mac, and never needed for any reason on any other machine. In fact quite the opposite: the hidden files serve NO purpose other than to waste bandwidth, time, energy, resources, etc.
This is a real problem because many people use Mac to zip files to share on the Web. Problem is that not everyone uses a Mac. So anyone downloading your zip files on their Windows, Linux, or other non-Mac is going to see all those hidden files and folders. Which are utterly useless to non-Mac devices and users.
*Important: The above command will remove all dot-hidden files, including files like .htaccess and other common/useful files. So if you want to keep some hidden files and only remove the ones added by macOS, use this command instead:
The above techniques show how to exclude hidden files when creating new zip archives. But what if you want to remove hidden files from an existing zip archive? Easy. In Terminal, navigate to the directory that contains your zip file and enter the following two commands:
And/or if you have multiple zip archives in some folder, and want to remove all hidden macOS files from all of them in bulk. Use Terminal to navigate to the folder and enter the following commands:
The first time i installed a new theme from my cpanel, i saw the MACOSX file and i almost deleted but i was scared the theme might misbeahave. Also is it true that someone can hack a website from this Mds file?
Working on a windows 10 computer. In Windows Explorer evry time I delete a _MACOSX file the Windows Explorer shuts down completely. When I reopen it, the MACOSX file is still there. I there a work around?
In Windows, you can easily drop your file contents in a folder and then transport it to the location of your choice on your personal computer. Zip files work in the same way as your standard folders. The only difference is that, with zip files, the contents are compressed into a single folder.
Zip files are a collection of various files that have been compressed into one file. Zip files are easy to send and transfer since they decrease the file size. Both Mac and Windows come with an inbuilt compression feature that enables you to zip files. The zip files put all your files in one place. The file archive will put all the compressed files in one place. Therefore, it is a suitable option when you want to have a single file. Any extension with a .zip or .Zip is a zip file.
You can save time by combining several files into one before you send them via email. You don't have to attach the files one by one. All you have to do is create a zip file and attach it to the email you want to send. Here are the steps for how to zip a folder on Mac.
The compressed file will have the same name as the original folder. The only difference is that it will have a .zip extension at the end. The zip folder will also be in the same folder as the original folder. Those are the simple steps to how to compress a folder on Mac.
You can open your zip file by double-clicking on it. You'll see all the files in that zip folder. Zip files are handled internally on the Mac operating system. But there are also third party tools you can use.
That is how you open a zip file on Mac. The archive utility tool for Mac opens and extracts the zip files and places them in the same folder as the zip archive. Opening zip files on Mac is a matter of double-clicking whether you use the Unarchiver or Mac's archive utility tool.
File extraction means uncompressing the zipped files. You can extract your zip files on Mac by right-clicking on the .zip archive. Next, choose "open". In case you are using a third-party tool, choose the option "open with" and select "another archive tool".
When I compress a folder or file by right click menu of Mac OS X, the archived file contains .DS_Store and __MACOSX folders. Because I share the archived file online for download, Windows users mistakenly trying to search the file in __MACOSX folder.
The problems happen when you send your .zip file to Windows or Linux users, or just use the general-purpose unzip program to unpack them. Those tools won't know that __MACOSX is special, and will just unpack it.
The simplest option is to use zip to pack up your zip file instead of the Mac built-in tool. zip won't create __MACOSX and your problem is solved. (You will lose the meta data in the process, but you probably didn't want it anyway.)
It is a GUI app, but has Applescript & Services support, with which you can run presets with your default settings - including omitting Mac-specific files like .DS_Store & __MACOSX. Possibly worth a look. 2ff7e9595c
