![]() ![]() Start with a well-known RAR extractor for Mac To use a preset, simply drop the files onto BetterZip and then click and hold either Save or Extract button in the top menu to select one of the available options. The price you pay is having to find and download a sort of WinRAR for Mac utility. While ZIP taps out at around 2 GB, RAR can take up to 8 EiB (the number so large it’s practically infinite). In terms of usability, RAR is not as popular as ZIP, but offers a better compression algorithm and, most importantly, works with large files. RAR itself is an acronym for Roshal Archive, as it was developed by a Russian software engineer Eugene Roshal. Unfortunately, you can’t open a RAR archive with Mac’s default tools due to the format’s closed proprietary nature. rar on Mac? Quickly Open RAR Files On Mac RAR, on the other hand, is a proprietary archiving format that requires a RAR opener for Mac to operate. ZIP has been around for more than 30 years and is easily readable by your Mac’s default archiving utility. There are literally dozens of archiving formats in existence, but it’s likely that you’ll only ever meet two: ZIP and RAR. This file format's primary purpose is data compression to save space.Ĭreating RAR files is only possible with licensed commercial software, like WinRAR for Windows or command-line RAR (also supports macOS) Eugene Roshal developed the format in 1993, and the name of the format is short for Roshal Archive. The first goal relies heavily on a compression algorithm and thus differs from format to format, whereas the second goal is equally achievable by all popular archivers on the market. ![]() In general, archives help us achieve two essential goals: decrease file size and unite a group of files into a single package. But few of us stop and think why exactly do we do this. Occasionally, we might be even packaging and distributing archives ourselves. Both Archive Utility and the zip command line utility discard ACLs.Compress and unpack any files on Mac with Archiver.Īll of us from time to time receive digital archive packages, whether they are downloaded online or get sent over by our friends. 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. Normally you can just discard the OS X-specific metadata, but to see what metadata files contain, you can use xattr -l. 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. _ that are used to store OS X-specific metadata. The _MACOSX directory contains AppleDouble files whose filename starts with. ![]() 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.Īrchive 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. DS_Store files inside directories but -x \*.DS_Store does. $ unzip -l a\ 2.zip # I created `a 2.zip` from Finder before this 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. 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
