python zipfile模块 ZIP64

def zip_dir(dirname,zipfilename):
filelist = []
if os.path.isfile(dirname):
filelist.append(dirname)
else :
for root, dirs, files in os.walk(dirname):
for name in files:
filelist.append(os.path.join(root, name))

zf = zipfile.ZipFile(zipfilename, "w", zipfile.ZIP_STORED,allowZip64=True)
for tar in filelist:
arcname = tar[len(dirname):]
#print arcname
zf.write(tar,arcname)
zf.close()

zf = zipfile.ZipFile(zipfilename, "w", zipfile.ZIP_STORED,allowZip64=True)
上面的函数有四个函数：zip文件包含路径的名字，"w"/"r"表示写或者读，zipfile.ZIP_STORED表示存储格式（还可以是zipfile.zlib.DEFLATED表示压缩格式）,allowZip64=True这个参数是在处理大文件时使用的，默认为False。如果没有设置为True而处理大文件时会提示 zip file size require ZIP64 extensions.
