Strengths & Weaknesses
↑ Strengths
↓ Weaknesses
The official repository lacks comprehensive guides or tutorials, making it difficult for new users to understand how to use the library effectively.
Yazl does not handle files larger than 4GB due to its lack of ZIP64 support, which can be a significant limitation when working with large datasets or applications.
Yazl does not provide functionality to encrypt files within the ZIP archive, posing security risks when sensitive data needs to be included in the package.
