When compared to Mac OS extended, APFS has been optimized a lot in terms of encryption, so itвЂ™s more suitable for flash and solid-state drive storage.

Part 2: Which Is Better, APFS or Mac OS ExtendedДЄPFS file system was announced in June 2016 to replace HFS+ (also known as HFS Plus or Mac OS Extended) the latter was used on all Mac computers as the primary file system since 1998 to replace the previous HFS.Д¬hoose APFS for SSDs & Flash Storage Devices Two main advantages of HFS+ when compare to HFS are: It was released in 1998 to replace HFS (Hierarchical File System, also known as Mac OS Standard or HFS Standard), which is the previous primary file system in Apple computers. Unison is no good as it requires a network connection between the 2 machines (which most admins baulk at).Mac OS Extended (Journaled) also known as HFS+, HFS Plus or HFS Extended, is actually a journaling file system released by Apple Inc. Synchronization utilities are no good as they require a disk big enough to hold the entire directory. Then it would repeat the process in the opposite direction. Ideally, some little program or script would identify added or changed files, copy them to the flash drive, then put them into the corresponding sub-directory when the flash drive was connected to the other machine. The flash drive is not big enough to contain a copy of the entire directory, but can easily hold just the changed files. I currently do this manually by copying any changed files onto a flash memory stick and then copying them onto the other machine when I get home.

I need to keep a large (about 5GB) directory of pdf files in sync between a work PC and a home Mac, all sorted into appropriate sub-directories. This hint makes me realise I'm not alone in thinking there must be simpler solution to the problem of keeping a directory in sync between work and home computers, without having to lug an external hard drive around.

There are, of course, a number of GUI apps that would do the job, too (e.g., FileMerge), many of them shareware. Although Unison appears to have an option to turn off permission checking ( -perms 0, or -perms=0), I couldn't get it to work. To forestall some obvious comments, Unison would seem to be the ideal tool, but it lists hundreds of files that only differ in their permissions metadata (not important to me). This list gives me a good feel for the big picture before I start overwriting things: which files or subdirectories can be deleted, which can be synced (and in which direction) using rsync, and which should be carefully checked before replacing, in case changes need to be merged. Pipe the output through grep to remove mention of uninteresting files, and sort to tidy it up, e.g.:Дiff -qr dirA dirB | grep -v -e 'DS_Store' -e 'Thumbs' | This command will provide a nice list of files that occur in dirA but not in dirB, files that occur in dirB, but not in dirA, and files that differ between dirA and dirB. The trick is to use the -q option to suppress line-by-line comparisons in files that differ: In addition to rsync, one useful tool is the unix diff command.ДЄs mentioned in other hints, diff can not only compare two files, it can, by using the -r option, walk entire directory trees, recursively checking differences between subdirectories and files that occur at comparable points in each tree. I like to keep the home directories on my work (PC) and home (Mac) machines more-or-less in sync using a hard drive that I tote back and forth every few weeks.
