Hi @Biva
Maybe you need to check the file types that can be indexed and see if they differ from the "virtual" folders. For a list of file types that can be indexed, go to the Indexing Options control panel page and select Advanced > File Types.
The indexing process happens in three stages controlled by a Windows Search component called the gatherer.
In the first stage, the gatherer adds URLs to queues. The URLs identify items to be indexed, and the queues are merely prioritized lists of URLs. In the second stage, the gatherer coordinates other Windows Search and third-party components to access the items and collect data about them. Finally, in the third stage, the data collected is added to the index.
The files in your virtual folder might miss any one of the above stages and that might be the reason or them to be not shown in indexing options.
Hope this resolves your Query!!
