Hi Vijay,

You can use the same process as mentioned in this link. With slight modifications, you can get to download all attachments.

https://www.servicenowguru.com/scripting/download-attachments-zip-file/#comment-34336

Please note that the script might take time and if you want to limit to N number of records, you can do so in the below script.

Few points to Note

1. The count variable is added to the file name to avoid duplicate file names. If there are duplicate file names, the zip process will break.

2. The script is modified to simply query sys_attachment and download them in the processor. It is not capturing any parameters from UI action as such.

3. Create the UI action as a form button on any incident or any other table.

  var zipName = 'attachments.zip';
  var StringUtil = GlideStringUtil;
  var gr = new GlideRecord('sys_attachment');
  gr.query();
  if (gr.next()){
    g_response.setHeader('Pragma', 'public');
    g_response.addHeader('Cache-Control', 'max-age=0');
    g_response.setContentType('application/octet-stream');
    g_response.addHeader('Content-Disposition', 'attachment;filename=' + zipName);
    var out = new Packages.java.util.zip.ZipOutputStream(g_response.getOutputStream());
    var count=0;
    while (gr.next()){
        var sa = new GlideSysAttachment();
        var binData = sa.getBytes(gr); 
        //add counter so that the filename is NOT duplicate
        var file = gr.file_name+"-"+count; 
	gs.info("Entered into this loop"+file);
	addBytesToZip(out, zipName, file, binData);
        count ++;
    }
    // Complete the ZIP file
    out.close();
}

function addBytesToZip (out, dir, file, stream){
    // Add ZIP entry to output stream.
    out.putNextEntry(new Packages.java.util.zip.ZipEntry(file));
    out.write(stream, 0, stream.length);
    out.closeEntry();
}

I ran this in my dev instance and it worked fine. The script takes time to download all the attachments. To test the script, i suggest you break the loop above at 5 or 10 records.

Hello Vijay,

I have the same requirement to have the ticket number with the attachment. And we want all attachments for a table. Your code worked for one ticket at a time. Did you develop code that would do all the tickets into individual .zip files with the ticket name for each file?

Thank you,

Laurie
