Quick and easy way for the splitting files into any number of smaller files as well as joining components back into the original file for Windows. The number of files can be entered or calculated based on expected length of individual files (in bytes or number of lines for text files). Once file components are generated they can be emailed using default e-mail account and to any contact from the contact list (Outlook 2003 or 2007) or using SMTP directly. Owing to the file naming schema, joining components back into original file is only a two step process. Only one component needs to be selected and clicking on the Join button will simply activate that process.
