stream-unzip

stream-unzip

Python function to stream unzip all the files in a ZIP archive, without loading the entire ZIP file into memory or any of its uncompressed files.

To create ZIP files on the fly try stream-zip.

Features

In addition to being memory efficient, stream-unzip supports:

• Deflate-compressed ZIPs. The is the historical standard for ZIP files.

• Deflate64-compressed ZIPs. These are created by certain versions of Windows Explorer in some circumstances. Python's zipfile module cannot open Deflate64-compressed ZIPs.

• Zip64 ZIP files. These are ZIP files that allow sizes far beyond the approximate 4GiB limit of the original ZIP format.

• WinZip-style AES-encrypted / password-protected ZIPs. Python's zipfile module cannot open AES-encrypted ZIPs.

• Legacy-encrypted / password-protected ZIP files. This is also known as ZipCrypto/Zip 2.0. Decrypting ZipCrypto with stream-unzip is approximately 10 times faster than Python's zipfile module.

• ZIP files created by Java's ZipOutputStream that are larger than 4GiB. At the time of writing libarchive-based stream readers cannot read these without error.

• BZip2-compressed ZIPs.

• An async interface that supports both asyncio and trio (which uses threads under the hood).
