Quick and easy way for the splitting text files (fixed or delimited) 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 lines). 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. TMFSJ is performing a line Split and Join and therefore can split and/or join any text file and preserve integrity of every line. It also provides header processing functionality for split (insert to every component or skip it). If component files have header in every file join will keep only first one. On-line help and detailed documentation combined with intuitive user interface provides pleasant user experience. Supports drag-and-drop, multithreading, progress display, cancelation of active process etc. Paired with AFSJ Mobile it can easily exchange text data or spread sheets via e-mail, in close to real time between PC and mobile device (phone, PDA?), completely avoiding e-mail size limitations. At the same time AFSJM application effectively preserves available space on your mobile device.
