List Files/Directories in Zip by Index

Demonstrates how to iterate over the files and directories in a zip archive by index. Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const zip = try chilkat.Zip.init();
    defer zip.deinit();

    zip.openZip("qa_data/zips/sample.zip") catch {

    var i: i32 = 0;
    while (i < num_entries) {
        zip.entryAt(i, entry) catch {};
        // Note: In the ZIP file format, it is not required for a ZIP file to contain explicit directory entries.
        // However, explicit directory entries can be included for convenience and compatibility with certain ZIP file processing tools and software.
        // An explicit directory entry in a ZIP file is an entry that specifically represents a directory, rather than a file.
        // It usually has a directory name with a trailing slash (/) and zero-length content.
        if (entry.getIsDirectory()) {
            std.debug.print("{d}: {s} (directory)\n", .{ i, try entry.getFileName(alloc) });

    // Sample output:

    // 0: aaa/ (directory)
    // 1: aaa/pigs.json
