Python script to generate a text file listing all files from a given directory (including those in sub-folders).

directory-inventory.py

import os

# start editable vars #
outputfile	= "inventory.txt"	# file to save the results to
folder		= "C:\\Users\\[User]\\Documents"		# the folder to inventory
exclude		= ['Thumbs.db','.tmp']	# exclude files containing these strings
pathsep		= "\\"			# path seperator ('/' for linux, '\\' for Windows)
# end editable vars #

with open(outputfile, "w") as txtfile:
	for path,dirs,files in os.walk(folder):
		sep = "\n---------- " + path.split(pathsep)[len(path.split(pathsep))-1] + " ----------"
		print sep
		#txtfile.write("%s\n" % sep)

		for fn in sorted(files):
			if not any(x in fn for x in exclude):
				filename = os.path.join(path, fn)				
				print filename
				txtfile.write("%s\n" % filename)

txtfile.close()
