Hi @azizidahalan,
Welcome to Box Community, and we’re happy to discuss the Box content recovery with you!
Just so you know, for paid accounts we have 14-day grace period to restore your contents once deleted from your trash. However, this recovery grace period does not apply to Free accounts. We are unable to support file recovery for our Free Individual plan.
To easily manage contents in trash, please check out this article.
Hope it helps, and please let us know if you need additional help.
