CDDesigner Manual: Data Tracks

Data Tracks

Raw Image

A raw image is a file storing the content of a CD data track. This file includes the directory structure and the attributes and contents of all data track files. The raw image is exactly the data written to a CD-R track-at-once and can currently not be modified with CDDesigner.

See Open Raw image See Read CD

Directory Tree

The tab displays the directory tree as it will appear on the written CD-R.

Filenames

Filenames are converted automatically to fit the selected data track format and are shown as they will be written to the CD-R. So any file or directory has an original title (that equals the filename on the harddisc or the name that was entered by the user) and the title that is used on the CD. The entry attribute inspector displays both titles.

See Data Track Formats See Renaming

Entries

Entry is the common term for either a file or a directory. Each entry has a size and an estimated size, where the estimated size includes the space for the directory tree. The estimated size of a directory is the sum of the space needed to organize its subtree on the CD plus sizes of all its files and subfiles.

Attributes and the name of an entry cannot be modified, if this entry is determined by a superior entry which is a link to a folder on the harddisc.

Virtual Folder

Virtual folders are located on the CD only and shown in a golden color. Their names and contents can be edited and they are used to give the CD a senseful structure without building the tree on the hard disk and without unnecessary copying of data.

Links

An entry referring to a file or folder on the hard disk is called a link. If a link refers to a folder, any subentries are determined by this entry and cannot be modified by the user. They are actualized when checking the tree, sizing the folder, exporting the raw image or writing a CD-R. Links are added by selecting the file or folder in the Workspace and dragging them to the CD's icon or a virtual folder's icon in the data tab's directory tree.

On a Unix system the following folders cannot be written to a CD: /private, /private/vm, /private/tftpboot, /Net, /private/Net, /usr/template/client/tftpboot, /usr/template/client/vm and /usr/template/client/Net. Adding a link to one of these folders makes the entry inaccessible.

See Accessibility

Link Loops

If the selected format supports symbolic links, they will be used to handle link loops. In this case an entry which is a link to a superior folder will have a special icon:

Though CDDesigner does not display any subentries of this entry, the written CD or exported raw image will contain an endless link loop.

If the selected format does not support links, the raw image cannot be exported and CDs cannot be written.

Opening file

opens the selected file. This can also be done by double clicking the file in the data tab browser or by double clicking the files icon. Virtual folders cannot be opened.

Selecting in Workspace

selects the file in the Workspace's file viewer.

Cut, Copy, Paste, Delete

Any commands from the can be used with a single or with a selection of files and folders.

adds the copied selection as subentries to the selected folder.

Data Track Format

Any data track is based on a data track format which effects and extends the capabilities of the tree in its special way. Most extensions are found in the entrie's and Volume Descriptor's attributes inspector.
