Hi there, 

Welcome to Box Community and glad to help! 

Here's how you can transfer the folder ownerhsip:

• Log in to box.com and locate the appropriate folder.


• Open the folder and click the Collaboration Icon to the right of the folder name.


• Alternatively, you can open More Options > More Actions and select Manage Collaborators.


• Find the collaborator whose access level you would like to modify. You can search by name using the Filter Collaborators search box in the upper right.


• Under the Permissions column, click the user's access level to modify it. Select the appropriate access level from the dropdown that appears. If the access level is greyed out, you may not have the necessary permissions to modify that user's access level. 


• 
  

  If you are the owner of a folder, you can transfer folder ownership to a collaborator at any time. Simply follow the instructions above, and select Owner from the access level dropdown (this option is only visible to folder owners). The collaborator you designate will be the new "Owner" of the folder and your access level will be downgraded to "Editor". The contents of the folder will no longer count against your account's storage allowance.

  
  

Hope it helps!
