vvvP (Virtual Volumes View, Photo Edition) is a program that catalogs photographs, both in removable devices and in hard disks at the same time. Images can also be arranged in a single, virtual file system. Each folder of this file system can contain images from many disks.
vvvP is available for Windows, Linux and for OS X (Intel only). It is possible to share catalogs among many networked computers.
New features:
Better handling of broken images.
Added the ability to remove a fixed location in the “Fixed locations” window.
The image viewer window has been reworked, with larger improvements to the Linux and OS X versions.
Faster thumbnails presentation.
Added the ability to delete files and folders in the fixed and removable view.
Fixed a bug in the Linux version: it was not possible to assign correctly some images to a virtual folder. It was only possible to assign folders.
