Errors stop sync

Hi everyone, is there a way to stop errors stopping the sync and deal with them only at the end? I left my computer overnight hoping the sync would be finished and in the morning I come and find that an error has stopped it and there are still 16 hours left to sync. It works ok if you get an error and tell it to ignore all, but it will still stop if it comes across a different error. What would be nice is if I could set it so that when it encounters any error at all, it just continues and then tells me about it at the end. Is this possible? Thanks.

Ok, so I'm a dummy - I just stopped the sync and there is the option in the settings - just need to check the box. I hope this helps someone else though! This is the best and only backup software!

"there is the option in the settings - just need to check the box"
"The" option ? "The" Box ?
Glad you found it, next time be more precise or post a screenshot. Because as it is, nope, this "the box" "the option" doesn't help : anyone.

Same here. I was trying to sync 5 TB over night and it was interrupted by an issue at 0.5 TB.
I found this thread, but not the option to show errors at the end.

You can tell FreeFileSync (FFS) to ignore errors when saving the *ffs_batch sync configuration by checkmarking "Ignore erros" box.
Afterwards you can then check the sync-log to see the errors, if any.

Thank you. That sounds like a workaround.
At the very least "ignore errors" is pretty misleading, since the errors are not ignored, but logged. If a dev is reading this, IMO this could and should be changed to three behaviours:
"On error: ( ) show popup, ( ) log only, ( ) cancel"
And - independendly of that - the popup could be moved to the end of the syncing-process. Just like Windows-Explorer did some years back: If I copy a folder and an error occurs on the first file, Windows explorer moves on and asks for the correct way to handle the error at the end.
This way, if the user is away from keyboard, the process can continue as far as possible before waiting for user input.
FreeFileSync could be even better: show the popup immediately but continue in the background as far as possible anyway.

When checkmarked, errors are ignored in the sense that they do not block the progress of the sync,
as opposed to "show error dialog" (=your Show Popup, putting the sync on hold) or "cancel" (cancels/stops the sync completely).

That is exactly what FreeFileSync is already doing:
( ) log only = present Ignore Errors
( ) show popup = Show error dialog
( ) cancel = present Cancel
It is the FFS author's choice to create the hierarchy in the options.
Only if you choose to not Ignore Errors, a choice for one of the other two options becomes relevant.
But Zenju could also have offered the options as mutually exclusive.
