Box allows you to sort your content in a couple ways; size, date and name.
Note: Old Box Experience
This page refers to the old Box experience. In Box, hover over a single file or folder with your mouse. If the item looks like the following image, you are in the right place.
If the item does not look like the image above, visit one of the links below instead:
To view files in numerical order when using titles with numbers, simply choose 'View by' then select 'Name'. For numbering systems that are double digit or higher, "0" must be used to fill digit spaces for the numbers to display correctly. For example, if you have a list of items that goes to 15, use "01" instead of "1" for the order to display correctly.
