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.

Go

    success := false

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

    zip := chilkat.NewZip()

    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.
    recurse := true
    success = zip.AppendFiles("c:/temp/files_to_zip",recurse)
    if success == false {
        fmt.Println(zip.LastErrorText())
        zip.DisposeZip()
        return
    }

    zip.SetFileName(zipPath)
    success = zip.WriteZip()
    if success == false {
        fmt.Println(zip.LastErrorText())
        zip.DisposeZip()
        return
    }

    zip.CloseZip()

    fmt.Println("Success")

    zip.DisposeZip()
