SyncTwoFolders

MU> Error on the requirements here, the site says ≥ OS X 10.10.5 for the Intel version and I confirm it works on 10.14.

Does what it says it does. The options how to backup are also most useful, including Simulation mode.

SyncTwoFolders is a simple, nifty little app that does what it says: synchronizes the files in two folders. It is more or less self-documenting from within the app. You have to experiment with the options a bit to make sure it's doing what you want it to do. There is a "Simulation" mode which will show you the results of a sync without actually changing anything. This is shareware. The author (see his comment below from 2/19/20) seems like a nice guy. Please support him. -SB

This is a simple, nifty little program that does what it says: syncs the files in two folders. It works very well. Documentation within the app is minimal. You have to practice with the options a bit to make sure it's doing what you want. There is a "Simulation" mode to help. The author seems like a nice guy. Please support him. -SB

I hope it is as good as it appears. A bit hard to understand the features without more documentation. Wanting to know how to update B with A without deleting anything in B, just adding anything new, and updating anything newer.

I've been using it on OSX for years. It does what it has to do and does it well. There are many options for syncing folders both to external drives and to network places. EXCELLENT ! and to recommend.

Looks like a solid, reliable app. I have been using it for syncing the internal drive with the external drives planned for backup. My preferred backup is ‘source replaces target’, in order to avoid further complications. I would have welcomed sys backup too, something like iBackup (grapefruit.ch) in its glorious days.

This a fairly nice app, but the app's website says you need the "Zx_External" in the same folder in order to sync things. But you can't download the "Zx_External"! It pops up a login dialogue box requesting a user name and password to download. Or am I missing something?

Oh, if it only could have a scheduling option and can manage more than one task at time :-)

Does not work well with 10.14.3. Copies but can't see the time line as the spinning rainbow of death is constantly on. When I came back the computer was asleep and I had to shut down the app to see what was going on so it does not alert when finished. You have to run another simulation.

This product only allows me to run a simulation not an actual job, any reason why?

Will the APP work for keeping two Directories/Folders in sync? I have my photos in one Directories/Folders that is on a drive with a large structure of photos with dated Directories/Folders. What I want is like a back up of a copy of the 2 that are identical to each other. Will this do the trick? Thanks

This has been my go to app for years, but as another mentioned, now it simply does not work: High Sierra. I've sent donations to the author, as his work is appreciated. I can only hope he continues to maintain this fine program? IF he does, I'll send him another $5.00. If more people did, the incentive might mean a 2.3 version update, continuing the legacy. My personal thanks one way or the other.

Simple to configure and versatile app that does a really great job. It's free but well worth a couple of $ to support the developer!

Loved this application. Although the latest update (v2.2.3) hangs upon launch on my mac running OS 10.11.6, rendering it impossible to use. 3 stars for previous positive history.

Great app, especially for free. I am going to donate $20. Using it to sync two very large music folders on different Macs over my network and it does the job well. Simulation mode is a good idea if you are unsure. Good job!

A little oversight in SyncTwoFolders: it doesn't check inside packages, so if the dates of the packages are the same but the contents have changed it won't sync them (it happens in Scrivener's files and probably others...)

I've just tried SyncTwoFolders in a very specific situation where I had problems with other utilities (free and not): syncing a folder with another one located in a Boxcryptor encrypted folder inside Dropbox folder. Believe it or not, it's the only one I've tried that doesn't make Boxcryptor crash, give errors due to file names or else! It won't be my work horse, but for that kind of situation, I've adopted it! :-)

This looks like a fine program that is generously offered by the author with a donation request. I suggest downloading directly from the author's site following reports that this site sometimes adds unwanted software to its downloads.

I think this app looks great & I'll be happy to donate (I'd love to set it to work every evening automatically too) but it's a bit confusing - what do the little symbols & colours mean when i run the simulation - how can i tell what will happen if there is no key to explain?
