Step 1: Add a Folder Structure → Columns SL0-SL9

This is a REQUIRED step.

The first step is to identify the catalogue's folder structure. A folder structure is a way information is organized and stored. The Libraries uses a tree structure which is a directory of folders containing folders/files.

The SL columns set up the folder structure. The SL0 column is the name of the catalogue while the 
SL1-9 columns are sub-folders.

• Each folder name in the SL columns is determined by the manufacturer.

SL columns are located in the SAM tab of the Sample MHL Catalogue Template.
