They are as follows:

.vie(file):
This is the project's source file, containing all the question slides, imported images, audio, etc., embedded into this single source file. This vie file is what is opened and edited inside ViewletACE.

.vi~(file):
This is the project's backup source file. If needed, a project may be restored from the backup file by changing the last character from a "~" to a "e".

.swf(file):
This is the compiled Viewlet file (found in the folder named after the source file) that can be played back through a browser that contains a Flash (6.0 or better) plugin or through a Flash (6.0 or better) stand-alone player.

_viewlet_swf.html(file):
This is a sample HTML file created when a project is compiled. This file has the Viewlet embedded into it and is used to launch it in a browser.

.qvss(file):
This is the Stylesheet file. By default, it is stored in the ViewletACE Library folder under C:\Program Files\Qarbon\ViewletACE 2006\Library\Stylesheets.

Not at this time. However, you will have this capability with ViewletBuilder 2006, our next generation ViewletBuilder. In fact, Qarbon’s 2006 suite of products, namely ViewletACE 2006 and the upcoming ViewletBuilder 2006 and ViewletCam 2006 will share a common architecture that will enable cross-functional usage of projects and files. Furthermore, ViewletBuilder 2006 will allow you to open any Viewlet you that you have created using ViewletBuilder4 and “upgrade” them into a format that can be used with Qarbon’s 2006 products.
