Unzip Files in a Date Range

See more Zip Examples

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

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

function chilkatExample() {

    var success = false;

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

    var zip = new chilkat.Zip();

    success = zip.OpenZip("qa_data/zips/sample.zip");
    if (success !== true) {
        console.log(zip.LastErrorText);
        return;
    }

    //  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 unzip files having a last-modified date greater than 1-Jan-2017
    zip.MinDate = "2017-01-01T00:00:00Z";

    //  Also, only unzip files having a last-modified date less than the end of 2020
    zip.MaxDate = "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 unzipping.

    var numUnzipped = zip.Unzip("c:/temp/unzipDir");
    if (numUnzipped < 0) {
        console.log(zip.LastErrorText);
        return;
    }

    zip.CloseZip();
