# Within these folder there will be many files with guids as filenames. Making it non-user friendly
# to know the file of a specific environment/collection.
#
# The simple script below will rename the files by extracting the name within the contents of the file.

The Python script process the Draw.io library files and "extract" the images from within it. In my case, I want to save the images as SVG and PNG files.

import json
import xml.etree.ElementTree as ET
import os
import cairosvg
process_files = [
'Library-1.drawio',
'Library-2.drawio'
