Enable Attachments


Enables attachments on a geodatabase feature class or table. Creates the necessary attachment relationship class and attachment table that will internally store attachment files.


  • Attachments must first be enabled using this tool before they can be added using the Add Attachments tool.

  • If the geodatabase feature class or table already has attachments enabled, a warning message will be delivered and no processing will take place.

EnableAttachments example (Python window)

The following code snippet illustrates how to use the EnableAttachments tool in the Python window.

import arcpy
EnableAttachments example (stand-alone Python script)

The following script illustrates how to use the EnableAttachments tool in a stand-alone script.

Example: we have a folder of digital photographs of vacant homes; the photos
are named according to the ParcelID of the house in the picture. Let's add
these photos to a parcel feature class as attachments.

import csv
import arcpy
import os
import sys

input = r"C:\Data\City.gdb\Parcels"
inputField = "ParcelID"
matchTable = r"C:\Data\matchtable.csv"
matchField = "ParcelID"
pathField = "Picture" 
picFolder = r"C:\Pictures"

    # create a new Match Table csv file
    writer = csv.writer(open(matchTable, "wb"), delimiter=",")

    # write a header row (the table will have two columns: ParcelID and Picture)
    writer.writerow([matchField, pathField])

    # iterate through each picture in the directory and write a row to the table
    for file in os.listdir(picFolder):
        if str(file).find(".jpg") > -1:
            writer.writerow([str(file).replace(".jpg", ""), file])

    del writer

    # the input feature class must first be GDB attachments enabled

    # use the match table with the Add Attachments tool
    arcpy.AddAttachments_management(input, targetField, matchTable, matchField, pathField, picFolder)
except Exception as err:
