Compress a String and Save as a Gzip File

See more Gzip Examples

This example demonstrates how to use the CompressStringToFile method to compress a string and write the result directly to a Gzip (.gz) file.

The input string is first converted to its byte representation using the specified character set (in this case, UTF-8). The resulting bytes are then compressed using the Gzip format, and the compressed output is written directly to the specified file.

This method is convenient when you want to generate a compressed file from in-memory text without needing intermediate objects such as BinData or StringBuilder.

// This example demonstrates how to compress a string and save the result
// directly to a Gzip (.gz) file.

loo_Gzip = create oleobject
li_rc = loo_Gzip.ConnectToNewObject("Chilkat.Gzip")
if li_rc < 0 then
    destroy loo_Gzip
    MessageBox("Error","Connecting to COM object failed")
    return
end if

// The string to be compressed:
ls_InputStr = "The quick brown fox jumps over the lazy dog."

// Compress the string using UTF-8 and write to a file:
li_Success = loo_Gzip.CompressStringToFile(ls_InputStr,"utf-8","output.gz")
if li_Success = 0 then
    Write-Debug loo_Gzip.LastErrorText
    destroy loo_Gzip
    return
end if

Write-Debug "Compression successful."
Write-Debug "Gzip file written to output.gz"
