Extract attachments from ArcGIS file geodatabase

extract_attachments.py

#############################################################################
# Requirements: ArcGIS 10.0 or higher, Python 2.7 or higher
#
# Description: Give this script an attachment table in a file geodatabase,
#              and it will extract all the files and place them into the
#              folder you designate.
#
# Note: Since attachments can have the same file name (i.e. Image00001.jpg)
#       this script appends the attachment id to the file name so that every
#       file is uniquely named in the folder you designate.
