GNOME 2.22 Features

|

Check www.gnome.org for a detailed description of GNOME features and enhancements, with screen shots and references. GNOME releases new versions on a frequent schedule. Several versions since the 2.0 release have added many new capabilities. GNOME now has efficiencies in load time and memory use, making for a faster response time. Desktop search is integrated into the file chooser dialog. For laptops, power management has been improved along with battery monitoring. For developers, a new version of the GTK+ toolkit provides better documentation and improved development tools. With GNOME 2.22, the GNOME Virtual File System (GVFS) provides direct file manager support for virtual file systems, letting you access Samba shares and FTP sites directly.

GNOME File Manager Features
Nautilus is the official file manager for the GNOME desktop. You can find out more about Nautilus from the Nautilus user’s manual that is part of the GNOME User’s Guide at www.gnome.org. The Nautilus file manager, as part of GNOME, also has several new features added:

• Nautilus File manager now includes a disk usage chart when displaying properties for file systems. Images are displayed with their appropriate orientation using Exchangeable Image File (EXIF) camera information.

• Nautilus is now more integrated into other applications such as File Roller for archives, the image viewer for pictures, and the GNOME media player for audio and video. You can now preview sound and video files within a Nautilus window.

• Nautilus uses GNOME Virtual File System (GVFS) for remote file systems, which replaces GnomeVFS. GVFS uses the GO object-based abstraction layer for I/O (GIO). With GVFS, Nautilus can support FUSE user-based file system access. Applications no longer have to be written for GVFS access. Any application can access a GVFS-mounted file system.

• With GVFS, Nautilus now manages automounts for remote file systems. Access is stateful, requiring the user input a password only once, before granting continual access.
• Nautilus can burn files and ISO images to DVD/CD writers.

• Context-sensitive menus let you perform appropriate actions, such as extracting archive files. An Open With option lets you choose from a selection of appropriate applications. Multiple applications can now be registered for use with a file.

• The file manager can display network shares on local networks, using DNS-based service discovery. The file manager also supports access to password-protected FTP sites.

• The file manager can display audio tracks on music CDs with the cdda:// protocol and access connected digital cameras with the gphoto2:// protocol.
