How to Zip a Directory with Python (using zipfile)

3 New Member
I'm relatively new to python, and am trying to zip a directory containing several levels of files and folders. I can use the walk function to name each file in my directory, and I can use zipfile to zip a flat number of files in one folder, but I am having heck of a time trying to zip the whole directory. I want to zip it all to a file called "help.zip", and I want it to retain the original file structure.

Of my several tries, here is the latest:
Expand|Select|Wrap|Line Numbers
  1. import zipfile, os
  2.  
  3. def main():
  4.     zip = "help3.zip"
  5.     directory = "//groupstore/workgroups/documentation/test"
  6.     toZip(directory)
  7.  
  8.  
  9. def toZip(directory):
  10.     zippedHelp = zipfile.ZipFile(zip, "w", compression=zipfile.ZIP_DEFLATED )
  11.  
  12.     list = os.listdir(directory)
  13.  
  14.     for entity in list:
  15.         each = os.path.join(directory,entity)
  16.  
  17.         if os.path.isfile(each):
  18.             print each
  19.             zippedHelp.write(each,zipfile.ZIP_DEFLATED)
  20.         else:
  21.             addFolderToZip(zippedHelp,entity)
  22.  
  23.     zippedHelp.close()
  24.  
  25. #def addFolderToZip(zippedHelp,folder):
  26.  
  27.     for file in folder:
  28.             if os.path.isfile(file):
  29.                 zippedHelp.write(file, os.path.basename(file), zipfile.ZIP_DEFLATED)
  30.             elif os.path.isdir(file):
  31.                 addFolderToZip(zippedHelp,file)
  32. main()
  33.

Here's a script that I use to backup the contents of a directory and it's subdirectories. It can easily be adjusted to backup only the directory contents or files with specific extensions. The file path is saved in the archive.
Expand|Select|Wrap|Line Numbers
  1. import zipfile, os

  3. def makeArchive(fileList, archive):
  4.     """
  5.     'fileList' is a list of file names - full path each name

  7.     """
  8.     try:
  9.         a = zipfile.ZipFile(archive, 'w', zipfile.ZIP_DEFLATED)
  10.         for f in fileList:
  11.             print "archiving file %s" % (f)
  12.             a.write(f)
  13.         a.close()

  19.     If 'subdir' is True, recursively access subdirectories under 'dir_name'.

  21.         file names are added to the list.
  22.     If there are no additional arguments, all files found in the directory are

  25.         Only files with 'txt' and 'py' extensions will be added to the list.
  26.     Example usage: fileList = dirEntries(r'H:\TEMP', True)
  27.         All files and all the files in subdirectories under H:\TEMP will be added
  28.         to the list.

Thank you!! Yay. I used your script to make mine work and I'm getting a better understanding of recursive functions. That was definitely where my hangup had been. Thanks again!!

you can also do this, which is MUCH more concise:

Expand|Select|Wrap|Line Numbers
  1. def recursive_zip(zipf, directory, folder=None):
  2.     list = os.listdir(directory)
  3.  
  4.     for file in list:
  5.         if os.path.isfile(file):
  6.             zipf.write(file, folder, zipfile.ZIP_DEFLATED)
  7.         elif os.path.isdir(file):
  8.             recursive_zip(zipf, os.path.join(directory, file), file)

Nakubu,

Thank you for your contribution. Please use code tags when posting code in the future.

It's not a good idea to use list and file as names of variables. The built-in functions list() and file() will be masked until the objects are deleted.

I have a question. Is zipf an open file object? It would be helpful to others reading this thread if you would post sample code that creates the file object, calls recursive_zip(), and closes the file object.

here's a revised version:

Expand|Select|Wrap|Line Numbers
  1. def recursive_zip(zipf, directory, folder=None):
  2.     nodes = os.listdir(directory)
  3.  
  4.     for item in nodes:
  5.         if os.path.isfile(item):
  6.             zipf.write(item, folder, zipfile.ZIP_DEFLATED)
  7.         elif os.path.isdir(item):
  8.             recursive_zip(zipf, os.path.join(directory, item), item)
  9.  
  10.  
zipf is an opened zipfile.ZipFile instance. For example:

Expand|Select|Wrap|Line Numbers
  1. zipf = zipfile.ZipFile(zip, "w", compression=zipfile.ZIP_DEFLATED )
  2. path = '/Users/nakubu/some_folder'
  3. recursive_zip(zipf, path) //leave the first folder as None, as path is root.
  4. zipf.close()
  5.

I found Nakubu's function helpful, but needed to modify it in several ways. Hope this helps someone:
Expand|Select|Wrap|Line Numbers
  1. def recursive_zip(zipf, directory, folder = ""):
  2.    for item in os.listdir(directory):
  3.       if os.path.isfile(os.path.join(directory, item)):
  4.          zipf.write(os.path.join(directory, item), folder + os.sep + item)
  5.       elif os.path.isdir(os.path.join(directory, item)):
  6.          recursive_zip(zipf, os.path.join(directory, item), folder + os.sep + item)

Using the following, you can determine the size of a file: Dim fi As New IO.FileInfo(<Path to file>) MsgBox(fi.Length) .... but what about the size of a directory? The IO.DirectoryInfo object doesn't have a Length property. In is there a way in VB.NET to determine the size of a directory without having to resort to importing the Scripting DLL and using the FileSystemObject? Thanks.
