Solves the problems for me

I have been using computers since the early 90's and there has always been the problem of where my files are. Mine are scattered all around, waiting to be filed. I use different places for backup in general but some things I just want to keep a copy of by themselves, either temporarily or due to a special circumstance, like backing up confidential information on an external drive. Usually, it would involve a few hours of dedicated concentration to do copy jobs from one spot to another. And usually the copy job would choke if I tried to copy a whole bunch of files at once, which would lead to more time and concentration. With the sync app, all I have to do is run the sync (having set up the particulars), literally just clicking the button, and all the work is done for me. I don't have to navigate there and double check which are the new files I need to copy across to the backup place and then double check that they're all there. I don't have to do this for multiple folders. Just one click and I'm off.

Great program - Great price!

I was searching for a program that would enable me to back up some important files, but which were not stored on my main hard drive, which uses Time Machine for backup. I kept those files on one external disk. And, like they say, “if you only have one copy …you don’t have a backup.” So, I wanted to make two external drives serve as backups to the original drive. But I didn’t want to have to manually go through all the files to be certain that I’d copied over ALL, and any NEW files I had added.
It was then that I found "Sync Folders Pro,” (I opted for the paid version) which fit the bill perfectly. The instructions are a little confusing and require some time and effort to get the various concepts into your head. But I found that the Support for the program was excellent in that when I had some questions there were “almost immediate” answers sent to me. I was impressed!
I recommend this program to anyone who wants to sync files over two or more devices. Every imaginable way to sync is covered and a user would be hard pressed not to have satisfaction in the results.
The price is practically a “give-away.” It’s a great value for your money and it appears by the customer ratings that I’m not alone in my praise for a programming job well done. Sure! The interface could be improved, but the end result would still be the same!

It just works!

Remember when  would use that catchphrase? It didn’t always apply to our hardware and system software, but I can say that it does to Sync Folders Pro. Now I’m sure that there are cases that there are problems, but I’ve been using SFP for a few years to keep a server and a copy synced to another computer on my local network up to date. In my use, files change on both ends and I love the feature that keeps copies of files that should be deleted in a folder for inspection before deletion. SFP mounts the shared drive via Wi-Fi automatically to make things even easier.

The interface and documentation on the different modes of sync are located on the developers website using an easy to understand examples (and are also in the program). Worth taking a look at before using to become familiar with the modes. I did have an edge case and wasn’t sure if the software would accomplish what I needed, so I sent an email to Vadim and he responded quickly with a little script to help accomplish my task. Excellent customer service!

Vadim keeps updating and improving the app over the years and is well worth the price. Highly recommended!
