    I am setting the friendly filename with viewer.options.friendlyFileName = “MyFilename.pdf” but when downloading with the toolbar Download button it gives me the original filename (“123456.pdf”) from the document URL that was loaded.

    I’ve confirmed the viewer filename is set to the friendlyFilename by checking alert(view.fileName) in the onAfterOpen callback – this correctly pops up “MyFilename.pdf”.

    Please advise how to make the download button use the friendlyFileName (or some other way to specify the filename when this is clicked).

    Hi,

    The friendlyFileName is used when the new document is created or when the file name is not available.

    Refer to the documentation for reference:

    Is there any way to make the file that is downloaded when clicking the Download document icon on the toolbar have a custom filename that is different from the filename of the URL that was opened in the viewer?

    I was able to figure out an alternate way. It’s not ideal - I’d appreciate if download used viewer.fileName out of the box (not sure what viewer.fileName is actually used for in fact).

    Here’s my implementation if anyone else has the same problem.

    
    this.viewer = new GcPdfViewer('#myViewerDiv', { });
            this.viewer.toolbar.addItem({
                key: "custom-download-button",
                icon: {
                    type: "svg",
                    content: '<svg xmlns="http://www.w3.org/2000/svg" version="1.1" width="24" height="24" viewBox="0 0 24 24"><path class="gc-icon-color--text" d="M5 19.998h14v-2H5m14-9h-4v-6H9v6H5l7 7 7-7z"></path></svg>'
                },
                title: "Download document",
                checked: false,
                enabled: false,
                action: () => {
    		this.viewer.download(this.viewer.fileName);
                },
                onUpdate: (e) => {
                    return {
                        enabled: this.viewer.hasDocument && e.state.session.status === 3
                    }
                }
            });
            this.viewer.toolbarLayout.viewer = { default: ['$navigation', '$split', 'print', '$split', '$zoom', '$split', 'doc-title'] };
            this.viewer.toolbarLayout.viewer.default.splice(2, 0, "custom-download-button");
            this.viewer.applyToolbarLayout();
    
    	this.viewer.options.friendlyFileName = myFriendlyFileName;
    	this.viewer.open(myUrlWithNastyFileName);
