Node / Python to create zip of directory contents?

Packages
1

Does anyone know of a node (or python way) to create zip files using dynamo?

Ideally it would be able to:

  1. input a list of files or directories
  2. input the name of the zip
  3. input the location to save the resulting zip

I am not aware of a node to do this, but it certainly looks doable - the documentation on the zipfile module can be found here: zipfile — Work with ZIP archives — Python 3.8.16 documentation

(if you are using the older Python 2 format you may need to select that documentation version from the dropdown).

Give it a shot and see where you get with it. :slight_smile:

Hello @Bren - you can use the Shutil module for simple operations (i.e. Zipping an entire folder!)

import shutil #Import the Shutil module that offers high-level operations on files and collections of files

#Inputs
zipDirectory = IN[0] #Define the directory of files we want to Zip up
zipLocation = IN[1] #Define the location we want our Zip file to be created at
name = IN[2] #Define the name of our zip file
format = IN[3] #Define the format we want to use - either Zip or Tar

_zippedFile = shutil.make_archive(name, format, zipDirectory) # We use the Shutil module to make an archive

_move = shutil.move(_zippedFile, zipLocation) #Then we move that module to the correct location as, by default, it will be created in the Dynamo install location

OUT = _move #We then output the final result to see a success message!

I’m getting the error No module named shutil because I’m using Revit 2019 and Dynamo 2.0.3.8811.

To fix it, I tried installing python via their main installer package but dynamo still doesn’t know about shutil.

Is it possible in older versions of dynamo?

with zipfile python module

import sys
import clr
import System

pf_path = System.Environment.GetFolderPath(System.Environment.SpecialFolder.ProgramFilesX86)
sys.path.append(pf_path + '\\IronPython 2.7\\Lib')
import os
import zipfile

folderPath = IN[0]
zipName = IN[1]
zipPath = os.path.abspath(os.path.join(os.path.dirname(folderPath), zipName))

with zipfile.ZipFile(zipPath, "w") as zip:
	for root, dir, files in os.walk(folderPath):
		for file in files:
			if file not in zipPath:
				zip.write(root + "\\" + file, file)
				
OUT = zipPath

with Python Engines work on Net FrameWork 4.5 or above

import sys
import clr
import System
from System.IO.Compression import ZipFile, CompressionLevel
from System.IO import Directory, Path, File

folderPath = IN[0]
zipName = IN[1]
dirInfo = Directory.GetParent(folderPath)
zipPath = Path.Combine(Directory.GetParent(folderPath).FullName, zipName)
if  File.Exists(zipPath):
    File.Delete(zipPath)
ZipFile.CreateFromDirectory(folderPath, zipPath)
OUT = zipPath
