Box Admin reports can, when selecting few filters, generate a large quantity of output - sometimes 200+ csv files for a single report.

There should therefore be a 'pre-run' test in the background before the report begins generating, that checks to see if there would be more than (say)10x csv files created by the report if it were to begin with the current settings...

If so (akin to when someone attempts to move a considerable amount of Box content), a prompt/popup should appear warning the user that there will be a large quantity of output, and giving user two choices, Continue or Abandon (with the default focus on Abandon).

I recently ran a Folders and Files report for the whole of our enterprise account, and did not realise the size of the output until it was 'Uploading', and there was no longer an option to Cancel the report. The whole upload was 298!! csv files

Box Support were unable to stop the upload/completion of the report, therefore users would benefit from a WARNING BEFORE the report is generated, to prewarn that the output will be considerable
