Hi Anthony, 

Welcome to Box Community and glad to assist! 

Notes:

• When items are deleted from a collaboration folder, both the owner and the person who deleted the item can recover the items from the Trash. 


• If you are removed as a collaborator from a file or folder that you've deleted, you no longer see that item in Trash. To see the item in Trash, you must be again added as a collaborator to that item.

Can you reach out to the folder owner and have the owner to filter/search through his/her trash? 

To search through your Trash folder:

1. Navigate to your Trash folder.


2. Toward the top, click the Search Files and Folders
   


3. In the box that displays, enter any search parameters.


4. Check Only search inside of “Trash.”


5. Press Enter.

To sort and filter all items within the trash folder:

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.

Hope it helps!
