Hi Flor, 

Welcome to Box Community!

You can restore deleted items in your online accounts trash. 

The steps below apply whether you’re selecting from search results or from all Trash items.

1. Hover to highlight the row of the item you want. The More Options ellipsis (…) displays.


2. Click the ellipsis (...).  Then: 

• 
  
  • To return the item to its original location in Box, click Restore.
  
  
  • To delete the item permanently, click Delete.
  
  

3. At the prompt, click Okay.

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.
