# The intent of this script is to provide server owners the ability to 
# generate a list of old files on their server such as extra dimensions
# so they can be deleted at a later date.

# Uncomment the below variable if you want to pre-set your server directory
MC_DIR="/home/agedcraft/multicraft/servers/server4/"

# Uncomment to tell the script to either delete, or report the files
#R_OR_D="Delete"
