Which file compression format is best?
Q Which f ile compression and archive format should I use?
by NATHAN ROWLANDS
A This is largely determined by who’s going to decompress those archives, and what’s in them. For general use with other Mac and PC users, standard Zip archives are universally accessible and reasonably efficient. Use Archive Utility, an app hidden in /System/ Library/CoreServices/Applications or found using Spotlight, ensuring its preferences are set to use Zip and not Apple Archive, which is Mac-specific.
