Hi there,

Welcome to Box Community and glad to help! 

You may track your file's download activity by creating a User Activity report and setup a scheduled reports. 

To run your report: 

• From box.com, head over to Admin Console> Reports> Create report.
  


• Select User Activity and it will take you to another page. 


• And you may begin to filter it to the date range, files or folders and users/groups. 
  


• Under Action types please select File management and filter it according to the report that you need
  


• Lastly, click run to create a csv file for this report.

Additionally, 

• You may see an "Anonymous" user on the User Statistics report which shows when anyone who wasn't logged into Box took an action on a Box item. This can occur for various reasons:


• 
  Shared Links: Users do not need to be logged into Box to access a shared link. Thus you may see previews, uploads, and downloads by "Anonymous". This typically relates to shared link activity.


• 
  Email Upload: Users do not need to be logged into Box to upload via email.  As a result, you may see "Anonymous" making many uploads.


• 
  Embed Widget: Users do not need to be logged into Box to preview an embed widget on a website. Thus, you may see "Anonymous" previews.


• 
  API integration: you may see other "Anonymous" actions if you have an API integration that performs actions in your account.


• When uploads occur via File Request you may see the folder owner as the name of the uploader (as it is technically an anonymous uploader).  To identify uploads via a file request, navigate to User Activity Report > File Management > Uploaded and click View.  Then, under Details,  filter by Service = File Request.


• If you are curious for more details around an "Anonymous" action, run a User Activity Report for that action type and select the same date range.

Hope it helps!
