This is a review of the new Mac OS X Snow Leopard program Squeeze 'Squeeze is a background file compressor, which uses the new HFS-compression technology in Snow Leopard to transparently compress the folders you configure it to process. Mac OS will read those files normally, they will just take less disk space.' I'm trying to decompress a Mach-O binary which has been compressed using one of the compression algorithms in Mac 10.10's HFS+ implementation. Basically the file has the 'com.apple.decmpfs' attribute on it, which says that it is compression type 8. Then the compressed contents of the file are stored in the file's resource fork. That’s a right PITA and really strange for the usually user friendly Mac. If you want to try HFS+ compression from the command line – check out here. We found a nifty and cheap tool to use HFS+ compression, but it’s disappeared. Outlook for Mac data folder location. Outlook 2016 for Mac puts the data folders in the users.
