The Video/File Merger Tool is a simple online tool that allows you to paste many URLs (Video or File Segments) into the following textbox. The server will download them one by one in turn and merge them into a single file for you to download. The merged target file will be kept in the server for no more than 48 hours. If any errors occur during downloading and merge file segments, the error will be shown and no file will be given.
