Batch extract attachments from File Geodatabase into individual folders based on features

[ColinBourne1]

Just wondering if anyone has a script to batch extract attachments from a file geodatabase and save them into individual folders based on the point/lines or polygons that they are attached to?

Kind Regards

Hello Collin,

There is a technical article which goes through process of batch exporting attachments from a feature class in ArcMap. The script runs per feature class so you would need to run it multiple times for each point line and polygon feature class. The script also allows you to define an output directory for each attachments table.

Hope this helps!

Thanks,

I do it this way.  I get the names via relates since I need to.

# Name:        Survey123 Export Photos to File System.py
# Purpose:     Exports the photos from the Survey123 Photos form from a exported GDB
#               Assumes state dir is already there
#               Will check for and create PrimaryKey dir if needed
#               For now it will overwrite every file as it goes.  Plus and minus to this.
