To unzip an archive into a specific folder, use the SevenZipFile class :
If your task is performance-heavy (e.g., compressing terabytes of data), it is often faster to call the official 7-Zip CLI using Python's subprocess module rather than using a pure Python library. pyth.7z
with py7zr.SevenZipFile('backup.7z', mode='w') as archive: archive.writeall("my_project_folder/", "project_backup") Use code with caution. Copied to clipboard To unzip an archive into a specific folder,
with py7zr.SevenZipFile('secure_data.7z', mode='r', password='your_password') as archive: archive.extractall() Use code with caution. Copied to clipboard 3. Comparison: Why 7z for Python? High (30–70% smaller) Encryption AES-256 (Robust) Header Security Yes (hides filenames) Compatibility Requires 3rd party tool 4. Advanced: Using the Command Line Copied to clipboard 3
The most popular way to handle .7z files in Python is through py7zr . It is a complete library that doesn't require the 7-Zip software to be installed on your machine. pip install py7zr Use code with caution. Copied to clipboard
One of the main reasons people use 7z is for high security. To open a password-protected file:
