please help

Hi Upasika, 

Welcome to the Box Community, we're happy to help!

I understand that you need help to restore deleted files from your trash folder.

We checked your account and it looks like you're on a Free Personal plan. Unfortunately,  we are unable to support file recovery for users of our free plan as stated on this article:  https://support.box.com/hc/en-us/articles/360044196093-Managing-Trash  

Contact Box Product Support immediately if the content you deleted is no longer in your Box Trash.   When Box purges your trashed content there is still a 14-day grace period for paying customers, during which Product Support can recover your content.  Beyond this 14-day grace period, however, files or folders purged from your Box trash may not be recoverable and may be lost forever. Please note that this recovery grace period does not apply to Free accounts. We are unable to support file recovery for our Free Individual plan. 

The investigation to determine if the contents you deleted is recoverable would require a paid subscription. You have the option to upgrade your current plan and you will be able to submit a case to Product Support, and the team can look if your files are recoverable.
