Overview

Table Columns
Directory	data	Unique-identifier for this directory entry.
Directory_Parent	TARGETDIR	Directory(column-id) of parent directory. Null means this current row represents the root TARGETDIR of the installation.
DefaultDir	data target:source .source:.target	The name of the directory. (by default both src/dest). Periods indicate directory references the parentdir directly, rather than a subdirectory within it. source appears to refer to the MSI installer itself.

Directory table entries represent a mapping of every individual directory that will be created in your installation.

• Only one directory is allowed without a Directory_Parent - this indicates the top-level target install directory
• Every non-null Directory_Parent references another entry's Directory id.
