1.To edit a file extension object, users load the list of existing extensions by calling the file extension view within the Visual Designer mode of PackDesigner.

 

2.Clicking on the list item of the object that has to be modified displays its details in the editor panel on the right hand side of the RayPack application screen.

 

The following properties of the extension object may be manipulated:

Basic Properties

Extension

A file extension is basically a string of 1 to 255 signs length. Internally, it is stored in a column of type text, which allows any kind of string. Logically, file extensions have to be entered as alphanumerical string, without leading period or special characters.

 

Since some file systems limit the length of valid file extensions to three (FAT) or six (VM/CMS) characters, it is recommended to make sure that the extension matches the target file system restrictions.

 

The combination of values for extension and component must be unique within the current packaging project. Therefore, if a new extension value is entered, which is already used for another extension related to the same component, the extension input field is marked with red background color, and the new value cannot be saved. Please hover over the input field with the mouse pointer to reveal a tool tip with additional information on how to solve the issue.

 

Component

Select one of the components from the offered list.

 

Again, the combination of extension string and component must be unique within a packaging project, therefore trying to change the component property is only successful when the new value pair is unique.

 

Feature

When a file extension object is created, RayPack automatically sets the value for the Feature property to the first found Feature object that is assigned to the component defined for the file extension object.

 

To change the current setting, users pick one of the offered Feature objects from the selector control menu, or use the create new button (*) at the right-hand side of the selector control to create a new feature. Please be aware that the combination of feature and component selection has to be valid in order to prevent later issues during package run-time.

Tab PROGID + MIME

ProgId

To change the current setting, users pick one of the offered ProgIds from the selector control menu.

 

If the desired ProgId does not exist yet, a new ProgId may be created by clicking on the create new button (*) at the right-hand side of the selector control. Clicking the button opens the dialog for entering new ProgId data rows into the Installer database.

 

 

MIME

To change the current setting, users pick one of the offered MIME objects from the selector control menu.

 

If the desired MIME does not exist yet, a new MIME may be created by clicking on the create new button (*) at the right-hand side of the selector control. Clicking the button opens the dialog for entering new MIME data rows into the Installer database.
