#Purpose: Delete intermediary files in dike process
#Context: Classified1 and Classified both produced some dike and pertinence structures and we need to model the data to be standardized to BCGW.
#Context: Current dikes will be archived once the data cleanup is complete.
#Warnings: The script will fail if you have a field with an intial character length more than 30.
#Prerequisites: The data must be copied in the same directory as the script, in a folder named, "dikes_for_processing"
# There must be no coded-domain-to-text fields in the resultant line FC.
