Fixed and removable locations

This is an important vvvP concept, and you need to understand it in order to use vvvP at its best.

People usually store images in what vvvP calls removable and fixed locations.

A removable location contains data that is not always connected to the computer. A good example or removable locations are CD and DVD disk drives. You can put a disk in the drive, but most often it is empty. Each disk that you can insert in the drive is called a volume: when you catalog a volume you must give it a unique name that will identify it in the future. Data stored in a removable volume are usually not immediately available to the program.

A fixed location is a folder in the computer's hard disk that contains images that will be cataloged by vvvP. Images in a fixed location will be always available to the program. vvvP makes the assumption that usually images are stored in a few main folders in fixed disks, each one containing many sub-folders. For example, a usual approach is to create a new sub-folder each time images are downloaded from the camera.

vvvP can handle both a fixed and a removable location for each image, but you can decide to handle only one of them.

• If you only store images in removable volumes like CD/DVD disks, you only need to handle removable locations.
• If you keep your images in your hard disk and you don't want to track backups with vvvP you only need to handle fixed locations.
• If you store images in your hard disk and you also save them to removable volumes like CD/DVD disks you need to handle both fixed and removable locations. vvvP will know that the same image is available in two different locations.

This is only a short introduction to this concept: more information is available in the program's help file.
