Merge TAR with ZIP in Python

Various data compression techniques are used to reduce the size of files and folders for storage or transmission. Two commonly used compression formats are TAR and ZIP, each with its own strengths and use cases. But what if you need to combine these formats? In this blog post, we will explore how to merge TAR with ZIP in Python.

Python Library to Merge TAR with ZIP

Aspose.ZIP for Python is a feature-rich library that allows you to work with various archive formats including ZIP and TAR. You can use the library for creating, adding, extracting, and manipulating archives effortlessly. We will use this library to merge TAR file with the ZIP archive.

You can download the library or install it from PyPI.

> pip install aspose-zip

Why Merge TAR with ZIP?

Before we dive into the technical details, let’s briefly discuss why you might want to merge TAR with ZIP. Both TAR and ZIP have their unique advantages:

  • TAR: TAR is a file archiving format commonly used in Unix and Linux systems. It is ideal for bundling multiple files and directories into a single file without compression. TAR archives are often used for backups and packaging files for distribution.

  • ZIP: ZIP is a widely used compression format that not only bundles files and directories but also compresses them to reduce storage space and speed up file transfers. ZIP is supported on multiple platforms and is compatible with various archiving tools.

Merging TAR with ZIP can be beneficial in scenarios where you want to preserve the directory structure of TAR files while gaining the compression benefits of ZIP.

Merge TAR with ZIP in Python

The following are the steps to merge TAR with ZIP in Python.

  • First, load the TAR file using the TarArchive class.
  • Then, load the ZIP archive using the Archive class.
  • After that, loop through the entries of the TAR using Archive.entries collection.
  • Extract each entry from TAR into a BytesIO object using Archive.entries[index].extract(BytesIO) method.
  • Add the extracted entry to the ZIP archive using Archive.create_entry(string, BytesIO) method.
  • Finally, save ZIP archive using method.

The following code sample shows how to merge TAR with the ZIP archive in Python.
