Prevent downloading posts by size (Not showing "To small")

[avi111]

Hi
when I set filter by size that is grater then 5M profile on a group it is steel download this headers (and JUST mark them as "too small")
this generate unnecessary big DB files
Is their any way I can prevent adding this small files posts from registering in the group.DB3 file (without manually deleting them from the group)
I don't understand this behavior why showing them as "too small" when I don't want to see them at all.

this create BIG DB3 files making then very slow to search in.

this is like using filter for spam post and downloading them all and shewing them as "spam"

Please tell me how to download ONLY post that are bigger then XX in size without adding them in to DB3 file
Thanks
