FreeFileSync Forum

Update and final resolution... The issue does indeed seem to have been a network issue. Without going into all the sordid details, I simplified the network configuration on both the source and destination and gave my hypervisor a separate network interface rather than share an interface with the phy...

New information on the above issue: I have compared 2 folders that FreeFileSync has replicated. These folders are on two different PCs so the comparison is happening over the network. Each folder holds about 68GB of data with file sizes ranging from 544KB to about 5GB. I ran this comparison 3 times ...

I recently migrated a large amount of data from one computer to another using FreeFileSync. Out of an abundance of caution, I decided to perform a comparison of the data using the option to compare file contents. Out of 3,000+ files FreeFileSync identified 27 files as being different. I then re-sync...

Update: Maybe I simply did not wait long enough, because it now allowed me to install on the system where I was getting errors. However, I still would be interested in answers on how I can avoid this situation in the future.

I specialize in unattended setup of Windows and as a result, I reinstall Windows on my machines frequently. Because of this, FreeFileSync seems to erroneously think that I have the Donation Edition installed on 12 different machines (which I have NOT!). On the screen informing me of this situation, ...

LOL. Of course there had to be a way to do that already!

Thank you both for the response and such a useful product!

If there is already a way to do what I describe below, I would appreciate any info on how to accomplish this. For removable media such as a USB Flash Drive (UFD), etc. it is possible that the drive letter can change. To work around this, I love the ability of FreeFileSync to use the volume GUID sinc...

Thanks for the response. I had completely missed the Verify Copied Files option. That resolves my second scenario. In my first case what I was hoping for was basically the ability to perform a Compare by Content (just as you noted) after the copy, but to do so automatically after the copy. That coul...

Let me explain two real-world scenarios where this would be helpful to me: 1) I ran into a situation recently where I had an SSD drive that was failing on me. This SSD was the target of data that I was syncing from another system using FreeFileSync. I had no idea that I was having any corruption unt...

I have a sync job defined that syncs multiple different folders. As an example, suppose the following: SourceFolder1 <> DestinationFolder1 SourceFolder2 > DestinationFolder2 SourceFolder3 > DestinationFolder3 SourceFolder4 > DestinationFolder4 At least one of these folders has hundreds of thousands ...

I am synchronizing a directory structure between two computers that contains several hundred thousand files. When I open my sync job, FreeFileSync starts automatically performing a comparison between the two systems. I have to wait for the comparison to finish before I can click on "Synchronize...

Ugh. User error. The access denied was referencing a LOCAL hidden folder. I simply had to create a filter entry to omit this folder that I don't want to sync anyway and that solved the issue.

I created a job that would sync from a local folder to a network destination using FFS 11.0. Nowhere do I see an option to supply a user name and password to connect to the network destination, so, naturally, I get an ERROR_ACCESS_DENIED when I try to perform the sync. Where do I enter credentials t...

Thanks for the clarification. I have one rather old laptop that has a finicky touchpad. Sometimes when I double-click on something, nothing happens because it doesn't always pick up the double-click. For many programs it is evident pretty quickly that the double-click was not seen so I simply need t...

xCSxXenon, that's actually not true. You cannot move it from the system tray to the taskbar. It only shows up in the system tray while active and then disappears altogether. I also fail to see how giving the user an option to display a quick visual glimpse (again, as an option that can be turned on ...

I have a FreeFileSync batch icon my desktop (a .ffs_batch created by FreeFileSync). When I trigger a sync by double-clicking this icon there is no visual indicating that the sync was actually launched. I need to go down to the taskbar and then expand the system tray to see if the program is actually...

Thanks for the help. The suggested syntax is working perfectly for me.

I have a naming scheme in which I name certain files and folders with an "!" as the first character. These are special files and folders that I do NOT want synced to another location. In the past, when I used Robocopy to sync all my files, I would simply exclude all files that start with &...

Plerry,

Thanks for the help. Much appreciated.

I have a folder on system 1 that I am mirroring to system 2. This is a one way mirror from system 1 to system 2. I setup a real time sync with an interval of 30 seconds. Question 1: Every time it performs a sync, a status window showing the progress of the sync opens. Can I supress this somehow? Que...
