 # Make sure to create a '''Configuration Folder ''' of the type “Autoloader”. # Create a CSV file with 3 columns (file name, custom field ID, and the Level 1, 2, or 3 ID). # Create a ZIP file that the files you want to upload or replace. Make sure the ZIP file and the CSV file have the same name. # Go to '''Menu Icon ''' > '''Autoloaders ''' > Create an autoloader that points to the '''Configuration Folder ''' you created. Set the '''File Type ''' to “CSV, Text”. Under '''Record Type''', select the desired UTA. Under '''Item''', select the new “File Upload” option. Then select the desired Level 1, 2, or 3. Configure the column mappings as usual.
