When you have a large number of PDF files to attach, we suggest that you file no more than 20 - 25 files per entry.  This will help ensure your success.  If you have more than 30 files for a single filing, select the appropriate event for your first entry and attached the first set of PDF files. For each subsequent set of PDF files, select the Notice of Filing event which will require you to link back to your original entry and you will attach your next set of PDF files.
