> but it appears that FFS is not capable of doing this.
By now, you should have understood that it is not FFS, but rather Linux that is not capable of doing what you want.

It depends on what type of encryption is applied. As FreeFileSync (FFS) works at file-level, if your encryption is also at file-level, FFS will gladly sync files in their encrypted form. Similarly, if you can mount your encrypted drive or folder(s) as a seemingly unencrypted drive or folder (some en...

Zenju's E-mail address can be found at the bottom of the FFS Home page.

In Windows, next to typing \\nas\share1 in the FFS location window, you can also drag a folder from e.g. Windows (File) Explorer and drop it into the FFS left or right location window. I believe on a MAC you can do the same by dragging a folder from Finder and drop it into the FFS left or right loca...

Not an automatic one:

viewtopic.php?t=7690

But it seems you already discovered the manual way to do it.

Theoretically, files can have an identical checksum and still differ in content.
That is however very, very unlikely, and, as explained in said threads, not the reason why FFS does not use hashes.

> I am assuming in sync settings, this would just be the mirror option? Both the Update and Mirror sync variant will only modify your right-side location ; not your left-side location. The Update sync variant will not delete any item from your right-side location that does not (or no longer) exist i...

For good reasons, FreeFileSync (FFS) does not use hashes (as discussed in this forum in multiple threads).
Instead, FFS uses a plain bit-by-bit comparison.

The problem seems to be that you created an overlap between your two folder pairs. Your first right location is D:\ , your second one D:\Photos . But D:\Photos is obviously part of D:\ , so there is your overlap. I would expect FreeFileSync (FFS) gave you a warning to that extent. There are (at leas...

There is no reason to expect that the FFS estimate would be more accurate than what e.g. Windows (File) Explorer predicts.

Correct. Any Excluded or not Included files and folders are simply not considered for any sync actions. The deletion of all not \202?\ folders and their content from your backup seems a one-time action and should be not too hard to do manually. If you want, you could also use FFS: Leave your Include...

After running a Compare:
Tools / Export File List

You could consider using Versioning. That will retain all files deleted or overwritten (updated) by FFS, in a self-selected location, for as many versions as you select and for as long as you select.

In- and Exclude Filter definitions are relative to the root of your base locations.
If Main is one of your base-locations, you need to exclude
\FolderA\A_Exclude\
not just
\A_Exclude\

In- and Exclusion Filter rules are relative to the root of your base-locations. Because your base-locations are D:\ and E:\Backup (and not D:\Dropbox and E:\Backup\Dropbox ), you need to exclude \Dropbox\.dropbox.cache\ Your present exclude rule \.dropbox.cache\ would exclude the folder .dropbox.cac...

> If I drag a folder drop on the + icon, will automatic add another new path. If I drop on the address bar, then replace the exist path. Could make sense. The location dropped onto the "+"-icon would then obviously become the left-side location of the new pair. On the other hand, it saves ...

Assuming your Exclude Filter rule is setup and working correctly, said "marker_file" likely already pre-existed in your backup location. Excluding a file (or a folder that a file is in) from your sync will make FFS ignore that file; it will not make FFS delete any such file from your backu...

From the fair understanding of RAID that I have, the fact that you have your backup disks setup as a RIAD array should never cause the problem(s) you describe. RAID simply spreads your (unmodified) data across multiple disks, potentially, depending on the type of RAID (e.g. 0, 1 or 5) you use allowi...

> REQUEST: have FFS keep a central DB of files synced in a sync set including source and destination. FFS uses a database in each of its left and right base locations, not a central database. The reasons why are clear, and explained several times in this forum, upon the request of others to have a s...

Your video is exactly as I understood your feature request the second time. For your very specific case this may make sense. However, even then my consideration remains that the left- and right-side would need to behave differently for the same dragging action. When dragging multiple folders into th...

You can also just click the MINUS symbol to remove folder pairs from a sync. Reload the configuration without saving and it will be back to the original xCSxXenon, 08 Dec 2023, 18:55

That's what I wrote in item 1) in my initial reply.

That is the part I (already) understood the second time. But, assuming that feature would be added, then after creating your 10 left base-locations by dragging/dropping or copy/pasting your 10 folders (in one go) you would still need to define your 10 right-side base-locations one-by-one. That is, b...

If you use scenario 1) above: Simply make two copies of your sync configuration(s), a "work" version and a "backup" version. If you inadvertently would overwrite your "work" version, you can restore the correct configuration from your "backup" version. In scen...

Ah, now I get it!
But how do you imagine that?
You drag/drop 10 folders into your left-side base-location, and FFS magically invents the 10 right-side base locations for you?

That feature is already there:

By default, the FFS Compare results window only shows files for which sync actions (in any form) are required, and hides files it thinks are equal.
If you click the "="-icon mid below the Compare results, you can toggle the visibility of equal files.

> I haven't been able to find the directory looking option. Where is it?

Look into LockDirectoriesDuringSync

If only more recent files need to be compared and synced, you could try the time-span filter-option, which can be found in the Filter Settings (F7).
