Replace/Update a FIle in a .zip

See more Zip Examples

Demonstrates how to replace/update a file from a .zip. Note: This requires the entire .zip to be rewritten. Go

    success := false

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

    // First prepare a .zip and write it..
    zip := chilkat.NewZip()

    zip.NewZip("qa_output/abc.zip")

    // Add some files..
    charset := "utf-8"
    zip.AddString("a.txt","aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",charset)
    zip.AddString("b.txt","bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb",charset)
    zip.AddString("c.txt","cccccccccccccccccccccccccccccccccccc",charset)

    // Write to qa_output/abc.zip
    // This .zip contains three files: a.txt, b.txt, and c.txt
    success = zip.WriteZipAndClose()

    // -------------------------------------------------------------------
    // Open abc.zip, replace the content of the "b.txt" entry with something else, and re-write.
    zip2 := chilkat.NewZip()
    zip2.OpenZip("qa_output/abc.zip")

    entry := chilkat.NewZipEntry()
    if zip2.EntryOf("b.txt",entry) == true {
        entry.ReplaceString("This is the new content.  bbbbbbbbbbbbbbbbbbbbbb","utf-8")
    }

    // Write the modified .zip back to "abc.zip"
    success = zip2.WriteZipAndClose()

    fmt.Println("success.")

    zip.DisposeZip()
    zip2.DisposeZip()
    entry.DisposeZipEntry()
