thanks for the link! there's another workaround which is just to use file or folder versioning and set the max version to 1 with whatever max age you need, it's just less clean since it'd add an extra folder layer or rename the files. i'm just suggesting a small feature addition, since the functiona...

will just contain the very last version of deleted or replaced files. yes exactly. so it will keep one copy of all deleted files forever, which is where a max age limit could come in useful so that deleted files over a certain age are permanently deleted. as it is right now, old deleted files could...

I noticed that currently, if you select Versioning and Replace, it does not allow you to set a maximum age for the files. That means that the old versions can keep indefinitely adding up old deleted files taking up all the space. With Replace of course there'd not be any use for minimum or maximum c...

Oh thanks, yeah that makes sense. I suppose what I really want to know is whether it stops comparison of a file as soon as it sees the first different bit, or if it still compares the rest of the file anyway. Seems like it'd be most efficient to stop and move on as soon as it knows that the file has...

I'm curious how the content comparison works under the hood. Does it use hashing? straight up bit-for-bit comparison?

and particularly, does the comparison run through the whole file always or does it just break and start copying as soon as it sees the first bit that is different?
