Unfortunately the syntax for the functions in AppleFSCompression is far from obvious, especially since it is a private framework which means that there are no included headers for it (and it also means that it will probably remain closed source). However, looking into it further I found that the Bom framework makes a call to another private framework: AppleFSCompression. The first thing that I tried to do was figure out the system call used for compression ditto uses the private framework Bom to compress files.

HOW TO SWITCH TO THE HFS FILE SYSTEM IN OUTLOOK FOR MAC MAC OS

Any files that were not compressed in the System folder were left uncompressed for a reason! If you do try to compress your System folder further, then you will very likely end up having to reinstall Mac OS X. Here's some example output: A warning about using this utility do NOT try to compress the System folder. The -x flag does the reverse of -a, unflattening a file with HFS+ compressed data in the data fork to the destination file, then decompressed the destination file is the -d flag is given.

The -a flag flattens a HFS+ compressed file to the data fork of the destination file, decompressing the original compressed file afterwards if the -d flag is given. The -d flag decompresses HFS+ compressed files (similar to afscexpand, but sometimes more reliable). The -l flag lists HFS+ compressed files in a folder or if the -c flag is given, it lists the files that fail to compress. If the -k flag is given then compressed files will be checked after compression against the uncompressed files, and if any corruption has occurred then the file will be reverted back to its uncompressed form. Here's the usage information for it: The -c flag applies in place HFS+ compression to a file or recursively to a folder, with the option to specify the compression level (default is 9), change the default maximum size (in bytes) of files to process (default is 20971520, which is 20 MiB), and specify the minimum savings for a file to be HFS+ compressed. Since I submitted this hint I've been working on a solution for the lack of information about HFS+ compression files, by developing this command line utility: So you can combine this with Dropbox to save some local space for all those important files that you don't need very often. Handily, HFS Compression being very low level plays nicely with pretty much everything else except anything to do with developer tools - for some reason it really doesn't like compressing. So I'm saving overall about 20% of the space required which isn't bad for a directory that contains a lot of images and PDFs. Total number of items (number of files + number of folders): 108įolder size (uncompressed reported size by Mac OS 10.6+ Finder): 34519979 bytes / 34.8 MB (megabytes) / 33.2 MiB (mebibytes)įolder size (compressed - decmpfs xattr reported size by Mac OS 10.0-10.5 Finder): 27890264 bytes / 28.1 MB (megabytes) / 26.8 MiB (mebibytes)įolder size (compressed): 27902203 bytes / 28.1 MB (megabytes) / 26.8 MiB (mebibytes)Īpproximate total folder size (files + file overhead + folder overhead): 28242154 bytes / 28.2 MB (megabytes) / 26.9 MiB (mebibytes) Here's the result of compressing a directory of old files: The stops you compressing files for which there is no benefit eg media files, jpegs, zips and rars. The -s' sets the minimum percentage that must be saved by compressing. Its the size in bytes, so 5242880 bytes = 5MB. Since the uncompressed file must be held in RAM, there is a tradeoff here. The '-m' sets the size of the largest file to be compressed. The command I use with some useful extra switches: afsctool also allows you to manage file compression, and to report on the results.Ditto, the file command line management utility can create HFS Compressed files.It offers background compression, pausing and other nice features. Clusters which is a nice GUI built on Apple's compression technologies.Besides, afsctool works only for existing files, not newly copied ones.

Outlook 2016 for Mac puts the data folders in the users. We found a nifty and cheap tool to use HFS+ compression, but it’s disappeared. If you want to try HFS+ compression from the command line – check out here. That’s a right PITA and really strange for the usually user friendly Mac.
