I lost a folder

Hi there,

Welcome to the Box Community!

Why are some files missing? I didn't delete them. All users collaborating on a collaborative folder who have an Editor access level or above on the folder will be able to move, edit, add, and delete contents within this collaborative folder. If you notice that content is missing or in a different location within this collaborative folder structure, it is most likely that another collaborator on the folder moved/deleted the item from its original location.

I can't find a folder I was collaborating on and it's not in the trash. What happened to it?If a collaborative folder that you do not own is missing from your Box account, it is most likely that the owner of the collaborative folder has removed you as a collaborator on the collaborative folder. You will have to contact the folder owner of the collaborative folder to have them reinvite you to that folder again.

Is the content in your trash? Are you the owner or deleter of this content? When a file is deleted, both the person who deleted the item and the owner of the item will be able to retrieve it from their trash. The Trash is located under Bin-- you can also review this article for more details on this process:
