In the Format Manager main window, the folders at the top level on the Tree view represent format categories. Formats are displayed subordinate to the related format category.
You can rename, edit, add, or delete a format, but you cannot add or remove a format category. Format categories are pre-defined in the software. A format category is formatted data that represents text with strings; numbers with integers, fractions, decimals, and so forth; and measurements with inches, BTUs, ergs, ohms, and so forth. All format categories contain formats that the design software can use.
