With Mail Resender you can also split and merge files in some formats. It does this task smoothly, without visual hangings.

1. The first thing you must do is opening the source file you want to split. Just click on the button at the right of "Source File" field. 2. Now go to desired folder and select the file. Write your account name and its original key into appropriate fields.

3. As you can see, the program selects for "Destiny Folder" value the source folder automatically. You can change it clicking on the corresponding icon. The "Base Name" means the name used to create the segments. By default, this name is the source file name without the extension. NOTE: Base name field won't take effect if "Random base name" option is active.

4. Every time you open a file, the program loads stored options. It means that, if you want to change split options,  you must do it after opening the file. Why that mess? Because most times you will use stored values, so you won't open "Options" dialog at all. You'll see how this behaviour will save you time. NOTES: - If you want to change usual options only for a specific file, save it pressing OK button. These options will be active until you open a new file. - If you want these current options to be usual options from now on, press Save button. These options will be loaded every time you open a new file.
