The first classification, scalars, is a type that can only hold one item. Pure, or "Vanilla" AppleScript (AppleScript that does not depend on any third party extensions aka: OSAXen, nor applications) has three different classifications of variable types: scalar types, container types, and other types. This article is not meant to be an introduction to the language, but rather read by someone who has a working knowledge of AppleScript. This article discusses three classifications of AppleScript's variable types, examines methods of appending an item to a list, and then examines the different kinds of copy operations available to a scripter. To those that don't understand these different types, some of AppleScript's behavior, looks like bugs in the language, but this is rarely the case. Sometimes AppleScript behaves in ways that are unintuitive and often frustrating to those who don't understand what's going on. Learning how different types of variables work is an important step for any AppleScripter. These incantations are usually due to an understanding of AppleScript's data sharing mechanisms, which are thoroughly explained in this article. Those who know AppleScript well are very familiar with obscure AppleScript tricks, magical incantations to make their scripts run faster.

The third is the search view, click here for a Windows screenshot.The virtual view is a powerful tool that will let you organize your data in a logical way: it will save you a lot of searches. You can assign the same file to more than one virtual folder, and each virtual folder can contain files that are stored in different disks. You can create folders and you can assign physical volumes or folders to each virtual folder. In this view everything is organized as a single virtual file system. The second is the virtual view, click here for a Linux screenshot.This view shows the content of each disk, you can navigate in the folders structure and see the files contained in each folder. The first is the physical view, click here for a Windows screenshot.VVV can show the content of your disks in three different views: Data are stored in a relational database, designed to handle millions of rows, so retrieving your information will always be a quick task. VVV is very fast, even with very large catalogs.

You can exchange catalogs between Windows, Linux and OS X computers, and you can connect Windows, Linux and OS X computers to the same (Windows, Linux or OS X) server. VVV is available for Windows, Linux and for OS X (Intel only). The network server is simply a computer running a database server program. It is possible to share the same catalog, stored in a network server, among Windows, Linux and OSX computers. VVV also stores metadata information from audio files: author, title, album and so on. Each folder of this virtual file system can contain files from many disks so you can arrange your data in a simple and logical way.

Folders and files can also be arranged in a single, virtual file system. VVV is an application that catalogs the content of removable volumes like CD and DVD disks for off-line searching.
