Question 1

How to build minizip-ng with ZSTD support?

Accepted Answer

Enable the MZ_ZSTD CMake option; if the library isn't found, set MZ_FETCH_LIBS to automatically download and compile zstd. Run 'cmake -S . -B build' and 'cmake --build build' as per the README instructions.

Question 2

minizip-ng vs libarchive: which is better for ZIP handling?

Accepted Answer

minizip-ng focuses specifically on ZIP with modern compression and encryption, while libarchive supports more formats but may have less optimized ZIP features. Choose minizip-ng for dedicated, feature-rich ZIP manipulation in C.

Question 3

Can minizip-ng extract files from corrupted archives?

Accepted Answer

Yes, it includes a feature to recover the central directory if corrupt or missing, as mentioned in advanced operations. This helps salvage data from damaged ZIP files.

Question 4

How to encrypt a ZIP file with AES in minizip-ng?

Accepted Answer

Enable MZ_WZAES in CMake, then use the API to set passwords and encryption type. The README lists WinZIP AES support, but code examples are needed for implementation details.

Question 5

Does minizip-ng support Unicode filenames on Windows?

Accepted Answer

Yes, it uses UTF-8 encoding with legacy fallbacks (like CP437) for compatibility. This ensures proper handling of international characters across platforms.

Question 6

What are the performance trade-offs between compression methods in minizip-ng?

Accepted Answer

ZSTD offers good speed and ratio, LZMA/XZ provide high compression but are slower, and Zlib is balanced. The library lets you benchmark based on your data, but enabling all methods increases binary size.
