A product does not need to be open.
If you have just created an exchange set, it is already open and you can add files.
To open an existing exchange set for editing:
1. Click Select.
A Browse for Folder dialog box is displayed.
2. Select the folder or paste the path in the box.
3. Click OK.
If no product catalogue for the files is found, the Select Catalogue dialog box is displayed.
4. Select a catalogue from the list and click OK.
The exchange set is displayed in the Exchange Set Editor.
The base cell is listed first, followed by any updates then any external files.
