Learn how to utilize ng2-file-upload in Angular for uploading .ply files effortlessly!

I'm currently working on uploading various files using ng2-file-upload. I've been successful in uploading different file types like png and jpg, but I'm facing an issue with the .ply file extension. Can someone guide me on how to upload a file with that specific extension?

Here is the code snippet:

imga = "http://icons.iconarchive.com/icons/hopstarter/soft-scraps/256/Button-Upload-icon.png";

public uploader:FileUploader = new FileUploader({url: URL});
public hasBaseDropZoneOver:boolean = false;
public hasAnotherDropZoneOver:boolean = false;
public selectedFilesArray = [];
private selectedFile;

public selectFile(e: any): void {
    var target = e.target || e.srcElement || e.currentTarget;
    var value = target.innerHTML;
    this.selectedFile = value;
    this.selectAll = true;
    this.selectedFilesArray = [];
    this.selectedFilesArray.push(this.selectedFile);
}

public fileOverBase(e: any): void {
    this.hasBaseDropZoneOver = e;
}

public selectAllFiles(e: any): void {
    this.selectedFilesArray = [];
    if (e.target.checked) {
        this.selectAll = true;
        for (var item in this.uploader.queue) {
            this.selectedFilesArray.push(this.uploader.queue[item].file.name);
        }
    }
}
