Script to translate files and folders

Few days ago i bought an “old games” emulator, the problem was that all games names was in Chinese although all the menus was in English

I removed the memory card from the emulator and connected it to my PC, then i saw all games files (.zip) names was in Chinese, so i decided to translate file names to English and hope that the games list will also be in English

I looked for a program to do that in the internet with no luck, so i wrote a small python script to translate using google translate API, Here is how it looked like while the translate was running:

The script:

from googletrans import Translator
import os
import sys
import glob
import shutil
import ntpath
import time

def isEnglish(s):
  try:
    s.encode(encoding='utf-8').decode('ascii')
  except UnicodeDecodeError:
    return False
  else:
    return True
    
translator = Translator()
path=u'J:\\roms\\'

def walkdirs(path):
  rename(path)
  for root, dirs, files in os.walk(path, topdown=True):
    for dir in dirs:
      dir_path=path+dir+"\\"
      print("Moving to dir " +dir_path)
      sys.stdout.flush()
      walkdirs(dir_path)

 
def rename(path):
  files=glob.glob(path + "*")
  i=0
  for file in files:
    if isEnglish(file):
      print (file)
    else:
        i=i+1
        old_name=file
        try:
		  file_base=ntpath.basename(file)
		  file_arr=os.path.splitext(file_base)
		  file_name=file_arr[0]
		  file_ext=file_arr[1]
          new_name=ntpath.dirname(file)+ "\\"+translator.translate(file_name).text.replace(":","-")
		  new_name=new_name+"."+file_ext
        except:
          print ("Translating error")
          sys.stdout.flush()
          i=i-1
          pass
          continue
        try:
          print ("renaming "+ str(old_name) +" to "+ str(new_name))
          sys.stdout.flush()
        except:
          try:
            print ("renaming XXX to "+ str(new_name))
            sys.stdout.flush()
          except:
            print ("renaming XXX to YYY")
            sys.stdout.flush()
            pass
        shutil.move(old_name, new_name)
        time.sleep(.300)
        
  print (str(i) +" files translated")    

walkdirs(path)

from googletrans import Translator

import os

import sys

import glob

import shutil

import ntpath

import time

def isEnglish(s):

try:

s.encode(encoding='utf-8').decode('ascii')

except UnicodeDecodeError:

return False

else:

return True

translator = Translator()

path=u'J:\\roms\\'

def walkdirs(path):

rename(path)

for root, dirs, files in os.walk(path, topdown=True):

for dir in dirs:

dir_path=path+dir+"\\"

print("Moving to dir " +dir_path)

sys.stdout.flush()

walkdirs(dir_path)

def rename(path):

files=glob.glob(path + "*")

i=0

for file in files:

if isEnglish(file):

print (file)

else:

i=i+1

old_name=file

try:

file_base=ntpath.basename(file)

file_arr=os.path.splitext(file_base)

file_name=file_arr[0]

file_ext=file_arr[1]

new_name=ntpath.dirname(file)+ "\\"+translator.translate(file_name).text.replace(":","-")

new_name=new_name+"."+file_ext

except:

print ("Translating error")

sys.stdout.flush()

i=i-1

pass

continue

try:

print ("renaming "+ str(old_name) +" to "+ str(new_name))

sys.stdout.flush()

except:

try:

print ("renaming XXX to "+ str(new_name))

sys.stdout.flush()

except:

print ("renaming XXX to YYY")

sys.stdout.flush()

pass

shutil.move(old_name, new_name)

time.sleep(.300)

print (str(i) +" files translated")

walkdirs(path)

I had few problems:

Google limits the number of translates per day – you need to change your IP address after something like 500 translates (By restarting your internet router or by using a VPN (the error was – “JSONDecodeError: Expecting value: line 1 column 1 (char 0)“
Some of the names python even can’t show with print, so i added try to the ‘print’ command

Here is how it looks after:
