How to save zip file chunks according to a batch of files.

create_zip_chunks.py

import os
import zlib
import zipfile

from glob import glob


def compress(file_names: list):
    compression = zipfile.ZIP_STORED
    store_chunk_limit = 1_000_000_000  # 1 GB
    store_chunk_size = 0
    files_chunk = []
    count = 0

    for file_name in file_names:
        if store_chunk_size < store_chunk_limit:
            files_chunk.append(file_name)
            store_chunk_size += os.path.getsize(file_name)
        else:
            print(f"Compressing chunk {count} with {len(files_chunk)} files")
            with zipfile.ZipFile(f"place_to_save/chunk_{count}.zip", "w", compression) as zf:
                for file in files_chunk:
                    zf.write(file)
                zf.close()
            count += 1
            files_chunk = [file_name]
            store_chunk_size = os.path.getsize(file_name)


file_names = glob('path_of_files/*.jpg')
compress(file_names)
