今天学习了在WINDOWS上压缩一个文件夹,记录下来,以防忘了:
import os
import time
import zipfile
from os.path import join
def zipfolder(foldername,filename):
'''
zip folder foldername and all its subfiles and folders into
a zipfile named filename
'''
empty_dirs=[]
zip=zipfile.ZipFile(filename,'w',zipfile.ZIP_DEFLATED)
for root,dirs,files in os.walk(foldername):
empty_dirs.extend([dir for dir in dirs if os.listdir(join(root,dir))==[]])
for filename in files:
print "compressing",join(root,filename).encode("gbk")
zip.write(join(root,filename).encode("gbk"))
for dir in empty_dirs:
zif=zipfile.ZipInfo(join(root,dir).encode("gbk"+"/"))
zip.writestr(zif,"")
zip.close()
print "Finish compressing"
# 1. The files and directories to be backed up are specified in a list.
source = ['D:\\MLES\\database', 'D:\\test']
# If you are using Windows, use source = [r'C:\Documents', r'D:\Work'] or something like that
# 2. The backup must be stored in a main backup directory
target_dir = 'D:\\temp' # Remember to change this to what you will be using
# 3. The files are backed up into a zip file.
# 4. The name of the zip archive is the current date and time
target = target_dir + time.strftime('%Y%m%d%H%M%S') + '.zip'
# 5. We use the zip command (in Unix/Linux) to put the files in a zip archive
#zip_command = "zip -qr '%s' %s" % (target, ' '.join(source))
m=len(source)-1
for i in range(0,m):
target = target_dir + time.strftime('%Y%m%d%H%M%S') + '.zip'
zipfolder(source[i],target)
