Extract ZIP Files Without Preserving Directory Paths Using DiscardPaths

See more Zip Examples

This example demonstrates how to use the DiscardPaths property to extract files from a ZIP archive without recreating the stored directory structure.

When DiscardPaths is set to _TRUE_, all extracted files are written directly into the target extraction directory, and any stored ZIP path information is ignored.

This is useful when:

• Flattening ZIP contents into a single directory
• Ignoring stored subdirectory structures during extraction
• Extracting only the files themselves without recreating folders

Suppose the ZIP archive contains:

docs/readme.txt
docs/manual.pdf
images/logo.png

Normally, extracting the ZIP would create:

output/docs/readme.txt
output/docs/manual.pdf
output/images/logo.png

But when DiscardPaths is set to _TRUE_, the extracted files become:

output/readme.txt
output/manual.pdf
output/logo.png

The stored ZIP directory paths are discarded during extraction.

Swift

func chilkatTest() {
    var success: Bool = false

    success = false

    let zip = CkoZip()!

    // Open an existing ZIP archive.
    success = zip.open(zipPath: "example.zip")
    if success == false {
        print("\(zip.lastErrorText!)")
        return
    }

    // Discard stored ZIP paths during extraction.
    // 
    // When DiscardPaths = true, all files are extracted
    // directly into the target directory without recreating
    // the ZIP directory structure.
    zip.discardPaths = true

    // Extract all files to the output directory.
    // 
    // Even if the ZIP contains:
    // 
    //     docs/readme.txt
    //     docs/manual.pdf
    //     images/logo.png
    // 
    // The extracted files become:
    // 
    //     c:/output/readme.txt
    //     c:/output/manual.pdf
    //     c:/output/logo.png
    // 
    var numFilesUnzipped: Int = zip.unzip(dirPath: "c:/output").intValue

    if numFilesUnzipped < 0 {
        print("\(zip.lastErrorText!)")
        return
    }

    print("Number of files extracted = \(numFilesUnzipped)")

    zip.close()

    print("Files extracted successfully.")
