> it would really speed up things with a option to scan each sequaltially

That option is already available via the "Run a command" option, at the bottom of the Synchronization Settings (F8).
To your D: -> X: sync configuration, add a command that runs your S: -> Y: sync
and to your S: -> Y: sync ...

What is presently available, is the warning
"The following folders are significantly different Please check ..."
That warning is enabled by default, but can be turned on or off via FFS's main menu
Tools / Options and "Show details" behind "Show hidden dialogs and warning messages again"

If you have the Donation version installed, if you go to
Help / Check for updates now
a "Check for updates now" window pops up which, if you do not have the latest FFS version installed, will show you "FreeFileSync XX.YY is available" (where XX.YY refers to the most recent version). And at the ...

Could it be that you have a RAR file entry (e.g. *.rar ) in your Exclude Filter.

> In the program settings, the "safe file copying" checkbox has its own value for different users. These are general settings for the program.

The "safe file copying" setting is saved in each individual user's GolbalSettings.xml file, and can thus be changed at a per user level, not as a per sync ...

Read the LockDirectoriesDuringSync description.
When the LockDirectoriesDuringSync flag is set to "true" (the default value), you must have write access to both the left and right base location.
By the way: the same holds if you checkmark "Use database file to detect changes" (the default value) in ...

Were you speaking of ADS (Alternate Data Streams) here, aka, "meta-data"?
If so, then you would be correct that a hash compares a "file" (& not ADS).

I had to check, but according to Google SHA256 does not include/compare ADS-data.

For different reasons, FreeFileSync (FFS) writes files at the start of its sync or during its sync, that are removed when/after the syncs ends.

This can be a sync.ffs_lock file (see LockDirectoriesDuringSync )

Or it can be one or more temp-files.
Unless you have disabled "Fail-safe file copy" in ...

After running a sync in the GUI there is a notebook-like icon (left in field 11 of the Main Dialog Overview) that will directly show you the log.

See my reply to your viewtopic.php?t=13127

You can (at least presently) not enable or disable the Significantly Different warning per sync configuration.
Instead, you can use two (or more) different global settings for your different syncs.

Make a copy of your GlobalSettings.xml file , for the sake of example named ...

When in doubt, run (just) a Compare, review the proposed sync actions, and only if those proposed sync actions match your intended sync actions click Synchronize.

The SHA256 algorithm only reads and evaluates the actual binary content/payload of a file.
It does not compare file meta-data.

I don't know which OS you (Antonio.A) are on, but on Windows that Browse window only shows folders, and the two buttons at the bottom are "Select Folder" and "Cancel".
So it seems to be a MAC and/or Linux specific problem.

Change your Include Filter from the default * (=everything) into just the file you want to copy.
The simplest way to achieve this in a correct way is by running (just) a Compare , then select and right-click that specific file and via the context menu Include that file.

Never tried this myself, but ...
The Include/Exclude Filter Manual page suggests you should be able
to use an Include Filter of *: (replacing the default * )
Just run a Compare and see if your (equal) folders are still listed or not.
Please share your experience here.

Bottom-right in the Synchronization Settings (F8) you can choose to post-sync "Run a command".
It seems for you "On completion" or "On success" would be appropriate.
You can then define a single command line that performs your desired post-sync action, or use the command line to invoke a (multi-line ...

You can define a ComputerName specific Versioning folder. (That is, specific to the Computer that on which your FFS sync runs, not the Computer the file that gets deleted or overwritten by the sync was located)
Sticking to the example location in Versioning manual page , instead of using D ...

If you do a search in this forum on "Galaxy MTP" you find numerous posts on the same issue.
Particularly Samsung apparently severely messed up their MTP protocol implementation.
The general recommendation is to use FTP or SFTP instead of MTP.

> I want to back up only the files that are being updated.

Again, it is unclear what you mean, and that unclarity concerns two aspects in above quote.
• As asked before, but not replied to: what do you mean by "back up"
• What do you mean by "are being updated"

If you want to create a sync that ...

What do you mean by "backup file"?
Do you mean
a) a file created or updated by a sync in a (left or right) base-location or any of its subfolders, or
b) a file created via Versioning, as a previous version of a file updated in or deleted from a (left or right) base location or any of its ...

If all files with a name starting with 01 have the same folder depth to your left and right base location, you should still be able to do it.
As per your example:
1. \foo\01 myFolder\01 myFile.txt
2. \foo\01 myFolder\other File.txt
3. \foo\other Folder\01 myFile.txt

If foo is the direct child of ...

> Is the reason the destination is not cleaned on Exclude ... functionally inherent in the Sync paradigm or is it more a performance gain ...?

I am not the FFS author, but probably neither of the two.
It seems simply to be the choice of the author, and is implemented fully consistent with the ...

A similar question as just above:
Do these two scripts (only) delete all destination-side items that match any entry in the Exclude list
or do they also delete all destination-side items that do not match any entry in the Include list?

@switch and @xCSxXenon
Do these two scripts also delete destination-side items that are excluded per the Time Span or Min/Max File size function?
See e.g. viewtopic.php?t=11477

It seems the relevance of my earlier replies slowly sunk in ...

> But apparently if I don't decide what Excludes I'll need at the created Sync Job's first run then I can't Exclude it later.

You can Exclude it later, and from that point onward FFS will not sync it anymore, because you have excluded ...

The FFS GUI will not show a list of available sync configurations (in its Configuration window, by default top-left), but rather the most recently run sync configurations.
That list will be populated as you run more different saved sync configurations.

You can open any saved sync configuration via ...

> But where are they meant to be stored ?

You can store/save *.ffs_gui and *.ffs_batch sync configuration files in any location you have write access to.
Simply use the "Save as" icon or main menu File option in the FFS GUI, and select an appropriate location and name.
Along the same line, you can ...

FFS does not require the file system to be NTFS to efficiently replicate file renames or moves.
In order to efficiently replicate file renames or moves, FFS requires the left and right location to have stable, cross session file IDs.

>> Did you try if it works?
> Yes I did but it did not mirror the source.

Well, it should have, except for the two excluded folders.
If it did not, did you check the log-file? That file might give you clues as to why it did not sync correctly.
Make sure to always first run a Compare before an ...

Assuming your subfolders Pending Pings and Crash Reports are direct children of your Thunderbird folder, your setup seems like it should work as intended.
Did you try if it works?
Obviously, if you just use a single left-right folder pair to be synced, you can/must simply add the two lines \Pending ...

> Can I download the latest donation version or simply install the 14.2 version I already have and let it auto update?

Either of the two should work.
But for downloading the latest donation version you should use the link to your personal download page, as provided in the E-mail you received after ...

> so I think the author of freefilesync is unable to collaborate

It's quite a presumptuous statement that the author is unable to collaborate.
The author simply chooses not to collaborate

> Personally I will not work with ppl not collaborating.

That's your choice, like it is the author's choice ...

FreeFileSync (FFS) does not use hashes.
If you Compare by file content, FFS simply compares the full content of the left- and right-side file; the best guarantee that both files are identical.
Even more so if you make sure data buffers have been flushed since your last sync, e.g. by restarting your ...

> I also notice that the algorithm first copies to a temporary file name and once that is successful, it deletes the original and renames the copy.

If that does not suit your needs, in the FFS main menu goto Tools / Options and un-checkmark "Fail-safe file copy".

> And "apparently" neither do you.

What is that statement based on?
The fact that you don't understand what I wrote, does not mean I have no idea what I'm talking about.
Don't project your frustration about "apparently" being called a spammer on a volunteer that is trying to help you. In your own ...

If you run a Compare and then hoover your mouse over the icon mid between any of the items, FFS tells you why it thinks it needs to take the proposed sync action.
And, as written before, likely the timestamp of the right-side file differs from that of the left-side file, and hence FFS considers ...

@D.Affy
Apparently you run this FFS task as a scheduled task.
That information is nowhere found in your entries for this topic, but would have been very useful.
Obviously, the user under which credentials an FFS task is run must have read and/or write access to the locations involved in your sync ...

> Do you know why the above initial recommendation from AI doesn't work?

I suppose because of at least two incorrect assumptions in AI reply step 6.
• If there is nothing to synchronize (because everything is excluded per step 5) FFS will not perform any sync-actions ("nothing to synchronize"), so ...

Flatpack is not an official FFS distribution, and not supported via this forum.
For support, try the Flatpack community.

If identically named left- and right-side files have different timestamps, when Comparing by "file time and size" (FFS's default), FFS will consider such files to be different, even if their size (and even content) is identical.
Depending on your synchronization settings, this "difference" between ...

FFS simply copies or updates a file left-to-right OR right-to-left.
Your example with the goodhopeFM.doc file will not synchronize properly with FFS either, just like when both bookmarks.html files have changed since the last sync.

If each of your doc-file comprises records of all changes made to ...

Apparently you installed the FFS Standard edition on your laptop.

You have three options:
1) If you kept the installation files of your Donation edition, use those to also install FFS .
on your laptop
2) Click the link in the E-mail you received after donating
3) Open your installed FFS Donation ...

Likely, both bookmarks.html files have changed since their last sync.
Then FFS does not know in which direction to copy (left-to-right or right-to-left).

It seems more robust to export the bookmarks of each Firefox version and import those in the other Firefox version. See e.g. here.

When you hoover your mouse over the 7 symbols in the Statistics field (12) FFS tells you what the number below that symbol means.

I made a mistake:
All symbols but the middle symbol tell you the number of files (per category), and only the middle symbol the amount of data to be copied (in total ...

After running a Compare, in the field mid below the Compare results (field 11 of the Main Dialog Overview on the #Quick start manual page ) there appear icon-buttons for each non-empty compare result category.
Those icons also show the number of entries per category.
(Note: You can toggle the ...

If you hoover your mouse over one of the yellow/orange lightning symbol icons mid between each entry, FFS should give some info on why it thinks there is a conflict.

Did you copy that folder manually (outside FFS)?
You use a two-way sync.
Did you ...

Unfortunately the FFS In- and Exclude Filter does not support self defined ranges, like you could do with e.g. a regular expression.

But, you only need to create 13 entries, the [n-z] range.
For your first sync (the [0-9] and [a-m] range) you create the [n-z] range entries in the Ex clude Filter ...
