Sorry to bump. I just wanted to see if there was a rough sense of timeline on integration of this feature (≈6 months, ≈year, ≈10 years, decades, etc.).
A couple scenarios have emerged where I need to provision if a solution isn't in the shorter-term horizon.

Reread the thread. Found it over-complicated. I think XY should do a very simple basic synchronize, easy to understand, easy to do.
Code: Select all
State before sync: Folder1: ABC | Folder2: CD
Sync: Folder1 > Folder2
State after sync: Folder1: ABC | Folder2: ABC
Tactically that would include the following steps:
1) Delete all items in Folder2 that are missing in Folder1 (permanently, no recycler, no questions)
2) Copy all items from Folder1 to Folder2 that are missing in Folder2
3) Copy all items from Folder1 to Folder2 that are different in Folder2 (i.e. overwrite them, w/o questions)
What do you think?

What you describe is a one-way sync. So you don't plan a two-way sync (e.g. folder B has items that only exist there -> copy them over to A)?

OK, here an improved way of describing it:
Code: Select all
One way:
State before sync: Folder1: ABC | Folder2: CD
Sync: Folder1 > Folder2
State after sync: Folder1: ABC | Folder2: ABC
Two way:
State before sync: Folder1: ABC | Folder2: CD
Sync: Folder1 <> Folder2
State after sync: Folder1: ABCD | Folder2: ABCD
My question about "two-way" is this: In which direction is "C" overwritten?

That (should) depend on user selection.
Normally it's the last modified time (newer files overwrite older ones).
But specialized sync software have a lot of other options (file size, hash, attributes, don't overwrite older files with (newer) empty ones), etc.
My opinion:
At least times should be selectable (last modified, created, maybe last accessed)
Everything else is (maybe) too advanced for the normal user anyway

OK, so also in one-way sync we could have either of these (depending on user settings) rules:
3) Copy all items from Folder1 to Folder2 that are different in Folder2 (i.e. overwrite them, w/o questions)
3) Copy all items from Folder1 to Folder2 that are different and older in Folder2 (i.e. overwrite them, w/o questions)
3) ... even more rules ...

I think for a one-way sync this wouldn't be necessary.
1. Delete all files & folders in <destination> that do not exist in <source>
2. Copy over all files from <source> to <destination> that don't exist in <destination> yet
3. Overwrite all files in <destination> that are different from their counterpart in <source> (by time / size)
In this case I see no need for user selectable options
