A file descriptor describes a file and, optionally, the structure of the file. The file can be in both the Eclipse workspace and in the system to be attached.
The physical name (attribute Name_Physical) of the file does not have to be given in order to describe a file. This can be set by a tool output parameter at run time. If the physical name of the file already exists, a static value can be entered under this attribute. If only the structure of the file path has been defined, a dynamic path can be entered into the AWM using dynamic references (see
Variable references).
A further feature of a file descriptor is the type. The “workspace_File” type indicates files that should be saved in the workspace or are to be read from the workspace.

Description
|
| Has_Property

This relationship can only be used for the description of structured files (table structure).
|
| Has_Action
|
0..*
|
Relationship to an action descriptor. Used only if the file descriptor is of structure table and the table is part of a modeled dialog or an ISPF dialog. Then the actions appear in the context menu of the table items.
