'Mac zip compress without __MACOSX folder?

When I compress files with the built in zip compressor in Mac OSX, it causes an extra folder titled "__MACOSX" to be created in the extracted zip.

Can I adjust my settings to keep this folder from being created or do I need to purchase a third party compression tool?

UPDATE: I just found a freeware app for OSX that solves my problem: "YemuZip"

UPDATE 2: YemuZip is no longer freeware.

macos zip

Can be fixed after the fact by zip -d filename.zip __MACOSX/\*

Solution 2:^[2]

Inside the folder you want to be compressed, in terminal:

zip -r -X Archive.zip *

Where -X means: Exclude those invisible Mac resource files such as “_MACOSX” or “._Filename” and .ds store files

source

Note: Will only work for the folder and subsequent folder tree you are in and has to have the * wildcard.

This command did it for me:

zip -r Target.zip Source -x "*.DS_Store"

Target.zip is the zip file to create. Source is the source file/folder to zip up. And the -x parameter specifies the file/folder to exclude. If the above doesn't work for whatever reason, try this instead:

zip -r Target.zip Source -x "*.DS_Store" -x "__MACOSX"

I'm using this Automator Shell Script to fix it after. It's showing up as contextual menu item (right clicking on any file showing up in Finder).

while read -r p; do
  zip -d "$p" __MACOSX/\* || true
  zip -d "$p" \*/.DS_Store || true
done

Create a new Service with Automator
Select "Files and Folders" in "Finder"
Add a "Shell Script Action"

Solution 5:^[5]

zip -r "$destFileName.zip" "$srcFileName" -x "*/\__MACOSX" -x "*/\.*"

-x "*/\__MACOSX": ignore __MACOSX as you mention.
-x "*/\.*": ignore any hidden file, such as .DS_Store .
Quote the variable to avoid file if it's named with SPACE.

Also, you can build Automator Service to make it easily to use in Finder. Check link below to see detail if you need.

The unwanted folders can be also be deleted by the following way:

zip -d filename.zip "__MACOSX*"

Works best for me

The zip command line utility never creates a __MACOSX directory, so you can just run a command like this:

zip directory.zip -x \*.DS_Store -r directory

In the output below, a.zip which I created with the zip command line utility does not contain a __MACOSX directory, but a 2.zip which I created from Finder does.

$ touch a
$ xattr -w somekey somevalue a
$ zip a.zip a
  adding: a (stored 0%)
$ unzip -l a.zip
Archive:  a.zip
  Length     Date   Time    Name
 --------    ----   ----    ----
        0  01-02-16 20:29   a
 --------                   -------
        0                   1 file
$ unzip -l a\ 2.zip # I created `a 2.zip` from Finder before this
Archive:  a 2.zip
  Length     Date   Time    Name
 --------    ----   ----    ----
        0  01-02-16 20:29   a
        0  01-02-16 20:31   __MACOSX/
      149  01-02-16 20:29   __MACOSX/._a
 --------                   -------
      149                   3 files

-x .DS_Store does not exclude .DS_Store files inside directories but -x \*.DS_Store does.

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.

You can't.

But what you can do is delete those unwanted folders after zipping. Command line zip takes different arguments where one, the -d, is for deleting contents based on a regex. So you can use it like this:

zip -d filename.zip __MACOSX/\*

Solution 9:^[9]

Cleanup .zip from .DS_Store and __MACOSX, including subfolders:

zip -d archive.zip '__MACOSX/*' '*/__MACOSX/*' .DS_Store '*/.DS_Store'

Walkthrough:

Create .zip as usual by right-clicking on the file (or folder) and selecting "Compress ..."
Open Terminal app (search Terminal in Spotlight search)
Type zip in the Terminal (but don't hit enter)
Drag .zip to the Terminal so it converts to the path
Copy paste -d '__MACOSX/*' '*/__MACOSX/*' .DS_Store '*/.DS_Store'
Hit enter
Use zipinfo archive.zip to list files inside, to check (optional)

Solution 10:^[10]

do not zip any hidden file:

zip newzipname filename.any  -x "\.*"

with this question, it should be like:

zip newzipname filename.any  -x "\__MACOSX"

It must be said, though, zip command runs in terminal just compressing the file, it does not compress any others. So do this the result is the same:

zip newzipname filename.any

I have a better solution after read all of the existed answers. Everything could done by a workflow in a single right click. NO additional software, NO complicated command line stuffs and NO shell tricks.

The automator workflow:

Input: files or folders from any application.
Step 1: Create Archive, the system builtin with default parameters.
Step 2: Run Shell command, with input as parameters. Copy command below.

zip -d "$@" "__MACOSX/*" || true

zip -d "$@" "*/.DS_Store" || true

Save it and we are done! Just right click folder or bulk of files and choose workflow from services menu. Archive with no metadata will be created alongside.

Do you mean the zip command-line tool or the Finder's Compress command?

For zip, you can try the --data-fork option. If that doesn't do it, you might try --no-extra, although that seems to ignore other file metadata that might be valuable, like uid/gid and file times.

For the Finder's Compress command, I don't believe there are any options to control its behavior. It's for the simple case.

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.

Solution 13:^[13]

This is how i avoid the __MACOSX directory when compress files with tar command:

$ cd dir-you-want-to-archive $ find . | xargs xattr -l # <- list all files with special xattr attributes ... ./conf/clamav: com.apple.quarantine: 0083;5a9018b1;Safari;9DCAFF33-C7F5-4848-9A87-5E061E5E2D55 ./conf/global: com.apple.quarantine: 0083;5a9018b1;Safari;9DCAFF33-C7F5-4848-9A87-5E061E5E2D55 ./conf/web_server: com.apple.quarantine: 0083;5a9018b1;Safari;9DCAFF33-C7F5-4848-9A87-5E061E5E2D55

Delete the attribute first:

find . | xargs xattr -d com.apple.quarantine

Run find . | xargs xattr -l again, make sure no any file has the xattr attribute. then you're good to go:

tar cjvf file.tar.bz2 dir

Solution 14:^[14]

Another shell script that could be used with the Automator tool (see also benedikt's answer on how to create the script) is:

while read -r f; do
    d="$(dirname "$f")"
    n="$(basename "$f")"
    cd "$d"
    zip "$n.zip" -x \*.DS_Store -r "$n"
done

The difference here is that this code directly compresses selected folders without macOS specific files (and not first compressing and afterwards deleting).

Keka does this. Just drag your directory over the app screen.
