Owner and Co-Owner - View each others files

Hi ​@Devashish, 

Welcome to Box Community and I’ll be glad to discuss more about content sharing! 

All Box users, regardless of their account roles are subject to collaboration. Which means, in order to see each other’s Box contents. You still need to send them invitation(s) to grant them access to the Box files or folders you own. 

If you haven’t done this yet, please start by inviting collaborators: 

 To invite someone to collaborate in a file or folder:

1. Open the Share window. To do this, in your Box files view, hover over the row of the file or folder you wish to share.
2. On the right, click Share.
   
   
3. The Share window opens.
   
4. In the Share window, under Invite People, click Add names or email addresses.
5. Type a collaborator's name or email address.
   • As you type, Box anticipates your intended recipient and lists corresponding email addresses.  You can select the recipient you want, or continue typing the full email address.
   • When typing full email addresses, separate recipients by a horizontal space.
6. Click the Invite as drop-down menu. Box displays a list of roles.
7. Click the role you wish to assign to the collaborator.
8. (Optional) In the Message field, type a message of up to 750 characters for the collaborator.
9. Click Send.

Hope it helps! Please let us know if you have additional queries.
