Appointment file for billing company

I need to send the files that contain future patient appointments to my billing company through email. I can not figure out which files these are, could you please let me know which files these would be and possibly how to send them?

All the appointment files are kept under the folder:

C:/Program Files/Voicent/AutoReminder/appt

They are organized by year, month, and date. Each separate file represents a different appointment. They are internal files meant to be read by programs, but you should be able to tell the patient’s name and appointment start and end time from the file.

The other method is to do an appointment report. Select View > Call Report… from the program main menu, and select the date, then click the Save to File button.
