Zip Files in a Date Range

See more Zip Examples

Demonstrates how to use the Zip.MinDate and Zip.MaxDate properties to zip only those files with a last-modified date within a date range.

Note: This example requires Chilkat v10.0.0 or greater.

public class ChilkatExample {

    public static void main(String[] args) {
        // This example requires the Chilkat API to have been previously unlocked.
        // See Global Unlock Sample for sample code.

        Zip zip = new Zip();

        String zipPath = "c:/temp/qa_output/out.zip";

        // Initialize the zip object with the path of the .zip to be created.
        zip.newZip(zipPath);

        // The MinDate and MaxDate properties use the timestamp date/time string format.
        // Here are some examples:
        // YYYY-MM-DD (e.g., 2024-07-31)
        // YYYY-MM-DDTHH:MM:SS�HH:MM (e.g., 2024-07-31T12:34:56+02:00)
        // 2024-07-31T12:34:56Z (the "Z" denotes Zulu time, or UTC)

        // Only append files having a last-modified date greater than 1-Jan-2017
        zip.setMinDate("2017-01-01T00:00:00Z");

        // Also, only append files having a last-modified date less than the end of 2020
        zip.setMaxDate("2020-12-31T23:59:59Z");

        // You don't need to specify both MinDate and MaxDate.
        // You can specify only one or the other if needed.

        // The MinDate/MaxDate properties apply to all of the Chilkat methods for appending files.

        // Recursively append to the zip object the paths of the files and directories in a directory tree.
        // At this point we are not creating the .zip, nor are we reading the contents of the files.
        // We are simply appending references to the files and directories in the local filesystem
        // that will get processed when WriteZip is called.
        boolean recurse = true;
        try {
            zip.appendFiles("c:/temp/files_to_zip", recurse);

            zip.setFileName(zipPath);
            zip.writeZip();
        } catch (ChilkatException e) {
            System.out.println(e.getLastErrorText());
            return;

        zip.closeZip();

        System.out.println("Success");
