Follow these instructions to set how many files can be sent through a FileBox at a time.
2. Select the FileBox you wish to edit to display the options. Scroll down to ‘Maximum # of files per transfer’ and type in the number you wish to limit downloads to (up to a maximum of 9). Note: Choosing a value higher than 9 requires increasing the ‘Box Height’ value, otherwise the FileBox will not display correctly.
3. Click ‘update’ at the bottom of the page. The page will now refresh showing you a preview of your new FileBox with your changes.
