Multisession Format--Importing a Session from a CD
You can import a session to add to a CD that already contains at least one additional ISO session.
For the ultimate in control, Toast lets you import the directory of previous ISO sessions and then edit and make any changes you want. You can delete, rename, move, and reorganize any of the files and folders of the old sessions.
To import an existing session
1Make sure the CD is in your recorder.
2 In the Select ISO 9660 window, click the Import button.
3 From the pop-up menu, choose Import Session.
If there is at least one ISO session already written on the CD, the Import Session dialog box appears.
4 Select the session you want to import (usually the most recent session).
Note: If you import a session other than the most recent one, you won't be able to see any data from the sessions written after the one you have imported!
5 To specify how you want the session to appear in the new session's directory, click one of these options:
Merged: The name of the old session becomes the name of the new session, and the data of the old session becomes the data for the new session.
Put into a directory: The old session is put in a directory with its name. If you haven't selected data before importing the session, a new CD directory is created containing one folder which contains the data from the old session.
6 Click OK.
The imported session appears in the ISO directory window. Files already written on the CD are marked with a small CD icon by their name.
Modifying an Existing File Structure
At this point you can make these changes to the structure:
Move files and folders to another position.
Add or remove files and folders.
Rename files, folders, and the CD.
Change the visibility of files and folders.
Add new data to any part of the directory structure.
The way you arrange the data determines the layout of the CD once you write the new session.
Note: To conserve space, files already on the CD are not written to the CD again; the directory structure is simply altered to match your changes.
Removing an Imported Session
To remove an imported session from the ISO directory window, choose Remove Imported Session from the pop-up menu in the lower right corner of the window. All the files and folders from the imported session are removed from the window, leaving only new data that you may have added.
