Of course, if you have incredible amounts of patience, you can try to manually combine two folders by dragging and dropping the files in them. If you have another file named "Test" in Folder B, ditto will delete that file and move the one from Folder A.ĭepending on how big the folder is, it may take some time for this process to finish. That means, if you're transferring a file named "Test" in Folder A to Folder B. The other thing to keep in mind is that the ditto command overwrites any duplicate file in the destination folder. One character off could cause you to lose some of the data. Terminal is a powerful tool, so you should only use the commands in this article exactly as they're typed. Now, a couple of things to get into before you go over the instructions. If you're not afraid to get into Terminal, you can use the ditto command to merge your folders.

But don't worry, in this article you'll read about how to merge folders on a Mac without losing your files. What you'll quickly see is it's not as simple as just dragging and dropping the files. Some of those folders might have duplicate files or even different versions of the same file. Seems pretty straightforward, right? Not entirely. Have you ever tried to get your computer files organized only to realize you should merge some of your files? Or maybe you're collaborating with other people and want to combine all of your files and folders. But if you’re set on doing that on your own, check out the best tips and tricks we’ve gathered below.

Unison is no good as it requires a network connection between the 2 machines (which most admins baulk at).So if you want to get a duplicate-free Mac in the shortest amount of time – download Gemini 2. 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.
#MACOS DIFF FOLDERS PDF#
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.:ĭiff -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.Īs 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.
