File time and date sync issue

[cb22]

Hi guys,
I'm facing an issue where files are the same, just renamed, but FreeFilesSync wants to copy them again each time.

What am I missing ?
I try in 13.7 & 13.8 versions, same issue.

Thank you.

> ... just renamed ...

A Mirror sync makes the right-side equal to the left-side.
So, if you rename files, the next sync will (want to) straighten out the right vs. left differences you created.

• If you renamed left-side files, those renamed files will be copied left=>right, and the originally named right-side files will be deleted.
• If you renamed right-side files, those renamed files will be deleted, and the originally named files will be copied left=>right.

So it's not possible to use FreeFileSync with renamed files (right-side) at all ?
Other mode that 'Mirror sync' does the same.

In comparison tab, it said "Identify equal files by comparing modification time and size", not mentionning the name of the file. But I guess, the name is important too for FreeFileSync. Am I right ?

FFS only compares identically named files, in identical folder tree locations relative to your left and right base locations.

True for Mirror and Update sync, not for Two-way syncs.
But for a Two-way sync, the rename will be applied to the opposite side during the next sync. So, then ultimately both sides will have identically named files.

For a Mirror sync:
If you use the "Use database file to detect changes" option in your Synchronization Settings (F8), and rename files, the FFS sync may just rename the right-side files instead of deleting right-side and copy left=>right.
But the Compare result window will still show the same picture, as FFS has no dedicated icon for "rename".

This is not correct, a rename will be considered an update
To the OP, any changes made to the right side in a mirror sync will be completely ignored since you told FFS to ignore those changes by setting up a mirror sync

It's working with the option "Use database file to detect changes" and NOT in mirror mode (but Custom).
Thank you all for the help!

To clarify a few misconceptions:

But the Compare result window will still show the same picture, as FFS has no dedicated icon for "rename".

"Moved files" have a different middle grid symbol, but (as of now) are categorized under "updated" in the view filters below.

To the OP, any changes made to the right side in a mirror sync will be completely ignored since you told FFS to ignore those changes by setting up a mirror sync

That's incorrect. "Mirror" will undo any changes on the right(target) side, including "renames".

It's working with the option "Use database file to detect changes" and NOT in mirror mode (but Custom).

Just "use database to detect changes". Moved files will be detected in "mirror" mode just fine.

That is a more accurate way to say what I was intending to convey
