Easy Populate's Normal vs Add New Only vs Update Only

[Alliene]

I can't seem to tell any difference between the 3 options of Easy Populate's Upload/Import functions (Normal, Add New Only, Update Only). I need to pretty much clear out an old inventory and add new product. Which option would clobber what's there and replace with the new database?

None of them.
Truncate/Empty the database table first in phpmyadmin , then 'Normal' to upload anew.
[Though seems kinda pointless in such an old version of osCMax.]
