Great program ruined by malware in the installer.

about FreeFileSync · · 5 Helpful

I really loved this program but the malware introduced in the installer has caused me to abandon it. The last time I installed this program (on my fiancee's laptop) the installer got to the page asking to install some kind of adware. While reading through this page, after only a few seconds, the installer jumped to the next page and started installing Freefilesync (and, as I would eventually find out, the adware program I was trying to read about). My hands were not touching her laptop so I know I didn't accidentally hit a key. Just to be certain I uninstalled the program and ran the installer again. For the second time, I watched as the installer jumped to the next page after only displaying the option to opt-out the adware for a very brief few seconds. I, honestly, was not given enough time to reject the install of this adware (yontoo).

I intended to run a scan using Malwarebytes immediately after this but was in a hurry and had to leave to do something. I forgot about this issue and, within the next day, pop-ups and notifications for various obviously fake issues started displaying on her computer. I immediately ran a scan with Malwarebytes and cleaned up the mess that the adware/malware had made.

It is really sad to have to write off such a great program due to such a poor decision by the developers to support their work with malware.

Avoid OpenCandy

Comment by RobertL87
about FreeFileSync and Unchecky · Dec 2015 · 7 Helpful

Very good tool, but shame about the (optional) OpenCandy in the installer.
You can donate to get an installer without OpenCandy adware. Unfortunately, you have to donate for every update then, but you can choose the amount yourself.

Tip to avoid malware like OpenCandy and unwanted toolbars: install Unchecky.

There is no portable install anymore, and it is officially ad-driven, acording to their website.
I'd like to delete this comment, but there is no such option.

previously I wrote:

No malware in 7.3 portable install
Installed 7.3 and got no screen to opt-out nagware (which I was expecting), but seemingly no nagware as well. Either it was because I chose "portable installation", either they removed it.
However, marking that positive, for now.

EDIT:
While installing the same version on another win8.1 mschine, I was given an option to opt-out, presented on dedicated screen.

Avoid like the plague (since the installer include malware)

Well as another poster points out, yes you are prompted to install some adware ... but in the 6.15 version at least it's in small letters "hidden way" ... I noticed it a split second too late as I hit OK.

Too late ... now my internet access is hosed.
Very disappointing from what used to be a great software tool.

Don't trust software that does this ...

Easy to use, but no data integrity checks on copy operations

about FreeFileSync and checksum, MultiPar, FastCopy · · 1 Helpful

I loved this when I first used it because it's very simple and easy. Plus, it's available in the PortableApps suite, which makes everything convenient. I already had FastCopy, which does data integrity verifications to make sure there are no copy errors, but I didn't know FastCopy could also do synchronization. The only downside to FastCopy is if you want to check the file comparison results, it doesn't have basic file comparison features like sorting etc. But, I trust FastCopy so much that I normally don't bother to double check the comparison results, so FastCopy does it all for me now.

When I REALLY want to play around with file comparison, there are many available tools that can do it, and FreeFileSync is one of the best of them. My favorite thing about it is how easy it is to use. Although it won't do a data integrity check after a copy operation, it will do checksums on the entire group of files, but that can take hours if you have lots of data. If you only have a small amount of data that only takes a few minutes, then that's probably good enough. Just do another file compare after you run the sync, and FreeFileSync will tell you if there's an error, so you can try copying the files again. It's not ideal, but it does work.

For data intergrity checks, my favorite tools are Corz Checksum, and MultiPar. Corz Checksum is by far the fastest tool I have ever seen - it's so fast, it's ridiculous. I've had cases that took 20 minutes that Corz Checksum could do in seconds. I use Corz Checksum to quickly check for problems in my data, and if any are found, I can fix it with MultiPar. MultiPar can do what Corz Checksum can do, but it's not as fast, so I usually don't use it until after Corz Checksum detects an error.

The most important reason to use both Corz Checksum and MultiPar is because of bugs. I found a bug in Corz Checksum once, that MultiPar found for me. Bugs happen! You can never be too cautious, or use too many data integrity and backup strategies.

Easy to use and clear settings/options.
If you want to sync files in Windows 8's Program Files directories, you should open this tool with administrator privileges.

Don't use, if your privacy is important to you

about FreeFileSync · Mar 2013 · -2 Helpful

FreeFileSync is a great program, it fits my needs perfectly. I especially like the nice tree view, that shows what is going to be transferred, including size information. This is way better than the flat view most alternatives offer.

There is one thing I don't like at all however: It includes the OpenCandy spy- and adware. ( Information on OpenCandy: http://en.wikipedia.org/wiki/OpenCandy )
And of course there isn't a big warning sign, only the open candy license agreement is shown below FreeFileSync's license agreement. (Have you ever scrolled down that far and actually read the license? :-))

So if your privacy is important to you, then use some other program, or at least block FreeFileSync and it's installer in your firewall (which of course is not an option, if you want to sync over the internet).

Summary: Great program by itself, but includes spy- and adware.

Far better than other sync tools for my needs.

about FreeFileSync · · 1 Helpful

I was looking for something to backup new and updated games from my Steam library (over 200GB) to an external drive so I can uninstall games to free up space and not have to waste bandwidth re-downloading if I want to play them again.

With FreeFileSync, the scan/comparison results are presented well with lots of statistics, there are buttons to filter the results view with a single click, and I can exclude folders in the right-click context menu (sub-folders are not expanded automatically). The interface is kept simple by having certain elements context-based - buttons that don't have any use to your current task/step in the sync process are hidden. I accomplished what I was trying to do quickly and didn't need to refer to the help file.

The previous sync tools I had negative experiences with were DirSync Pro (too complicated) and Microsoft SyncToy (not complicated enough to be useful).

Backup tool - Excellent

about FreeFileSync · · 1 Helpful

This has replaced my data backup software (Acronis) with the feature "file-versioning". This allows you to keep a current full backup whilst archiving any changes/deletions. This feature can't be emphasised enough and is more useful than most backup software that starts with a full version then keeps incremental or differential archive formats. It can run as a batch file and used VSS. No good for OS imaging or disaster recovery of OS.

Does pretty much everything I need to do better than MS Synctoy. I had started off with that hearing good things until I found out it won't copy files that are in use. I'm using it to sync my XBMC database from my media center to my regular PC. It works like a charm. I also use it to keep my music synced across 2 computers (I like having it in both places) as well as my Portable Apps. It reads the changes ridiculously quick, copies files in use, and the interface stays relatively responsive.

If you're looking for the portable version, look in the v3.2 folder. That's where it paf package was.

No auto-deleting of synced files in both directions

about FreeFileSync and Allway Sync, Synkron, PureSync · · 1 Helpful

My personal impression: structured very clearly, and very impressing and simple user interface. But if You want to delete files on the other directory equal in what direction automatically, You cannot use it for synchronisation.
For this purpose there would be necessary a synchronisation data file in the synchronised directory, which FreeFileSync does not have and not need, because the deletion direction must specified from case to case. FreeFileSync is good for making identical copies of directories (Like backups in ONE direction)
Deletion automatically in both directions is possible with Synkron (Open Source), PureSync (Free for private use), totally perfekt with Allway Sync (but max. 20000 Files/month free, the only Sync Tool, able to sync Windows Mobile SD-Card or NAND-Memory and WebDAV and FTP-Online Memory direct adressable).
