find pdf file (or some exe file) in directories and copy it to another directory, python sample code

import os

import glob

from shutil import copyfile

files = []

start_dir = '/Volumes/input/'

output_path = '/Volumes/output/'

pattern = "*.pdf"

total = 0

for dir,_,_ in os.walk(start_dir):

files.extend(glob.glob(os.path.join(dir,pattern)))

for i,v in enumerate(files):

#found pdf files

print(total,i,v)

#extract filename only

filename = v.split('/')[-1]

#make new filename and output path

output_filename = output_path + str(total) + '_' + filename

#if file exist? then no copy

exist = glob.glob(output_filename)

#if not copy

if len(exist) == 0:

copyfile(v, output_filename)

#print out copied filename

print('copy! : ', output_filename)

#increase global count

total += 1
