Please be advised that there is 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.

Furthermore, I noticed that your profile is linked to a Personal Free account, please note that this recovery grace period does not apply to Free accounts, so I'm afraid we are unable to support file recovery for you.

Thanks for reaching out and stay safe!
