[Feature Request] Option if the replacing file is MUCH smaller than the to be replaced one

[meATffsForum]

or even of size 0.

You describe a case, but do not describe what option you are requesting (if the replacing file is MUCH smaller or even of size 0 than the to be replaced one).

I'm sorry - I made too few words as I thought it would be obvious ;)

The reason for the option:
If some source file has been unintentional, accidental or with evil intent
altered in a way that it's size is much less then the mirrored version,
FFS could help by giving a message before overwriting.

The option would be something like a check box and/or edit box:
check box for enable
edit box for limit % of orig file size
Example: Ask before overwrite a file with a newer one with less then 90% of orig size.
(Size 0 will always reported, except if former size was already 0).

FFS warns if the contents of the left and right base location is substantially different.
However, that is collectively and not on a per-file base.

For these sort of cases, FFS provides Versioning. This allows you to keep as many previous versions as you select, for as long as you select, in a location you select, of all files that are overwritten or deleted by your FFS sync.

What is "substantially different"?
When does FFS warn: before syncing, or after?

For these sort of cases, FFS provides Versioning.

I know about Versioning - it's something I don't need usually.
What I need is mirroring, and it would be nice to have it there (optionally)
if size of a file has drastically lessened (or even set to 0).
