Our business is catalog sales. We ship via UPS with their proprietary package. The shipping information is exported to a CSV file on the UPS machine. Our CSR's can access this file to get the most up to date shipping and tracking information. However, at times the shipping department closes earlier than the Customer Service Dept. and the UPS machine is not available. Prior to shutdown the CSV file located on the UPS machine is copied to our server.

Accessing the CSV file is handled in the following way:

if file(\\UPS\*.csv)
use the UPS machine csv file
else
use the Server csv file
endif

This does the job. However there is a significant delay returning the file() value if the UPS machine has been shut down.

Is there a more efficient way to do this?

Any assistance is appreciated.
