Missing files in various and multiple folders

Also already tried searching through Trash folders and nothing is there.

Hi there, 

Welcome to Box community!

Please note that you can filter content by items you own, or by items you’ve deleted.  To do this, directly beneath the folder label (Trash), click the Items I Own (or Items I Deleted) down arrow.  Then click the option you want.

• The Items I deleted filter displays all items you have deleted, regardless of who created or owns the item.
• The Items I own filter displays all deleted items you own, regardless of who deleted the item.

Tip

Filtering by Items I Own is helpful when trying to track down content that may have been deleted by a collaborator in a folder you own.

Thank you for posting!
