During analysis, $Recycle.Bin will appear to have $2$ versions of each file, why?

$1.$

Recycle Bin splits files into smaller parts, making it appear that there are $2$ versions

$2.$

When files are marked for deletion the soft link and hard link both appear in the Recycle Bin

$3.$

Files moved to the Recycle Bin will be duplicated, $1$ file to delete and $1$ to recover in case of an emergency

$4.$

Files metadata is stored seperate from the document itself once marked for deletion
