Portfolio recognizes and catalogs all file types, regardless of whether the file type appears on the File Types list. You only need to add file types to the list if you want to exclude a type that does not appear on the list, or if you will be excluding some types and including other types that do not appear on the list. Changes to the list are made on the Cataloging Options - File Types tab.
Tip: To catalog all File Types, select Catalog All Types from the File Types tab of the Cataloging Options dialog (Catalog > Cataloging Options).
To add a File Type:
Choose Catalog > Cataloging Options [or press Command+J (Mac OS) or Ctrl+J (Windows)].
Click the File Types tab to select it.
Click Add.
Enter the file type information, or click Same As... and locate a file of the same type. Portfolio will copy the parameters of this file type into the fields.
Click OK to add this file type to the list.
