Sims 3 Store Updates: I already have a Mods folder! [SOLVED]

My sister installed Sims 3 with expansions too.
When i tried to drag-drop the Mods folder to the Program files (x86)/Electronic Arts/The Sims 3 folder, a window shown up, and said, there is already a folder "Mods".
My sister said, maybe she downloaded, or created it somhow. What should i do?
Should i delete the folder which is already there, or if not, please tell me, where to copy-paste the files from the store update's Mods folder, which i downloaded.

Hello,

Please note you must copy the "Mods" folder to: (My) Documents\Electronic Arts\The Sims 3
and not to the game directory!

Oh! Sorry, i missplaced it.
Now i copied in Documents, and it's in the game, so thanks for help.


Mod edit: Problem solved, topic closed.
