GVFS
GVfs (abbreviation for GNOME virtual file system) is GNOME's userspace virtual filesystem designed to work with the I/O abstraction of GIO, a library available in GLib since version 2.15.1. It installs several modules that are automatically used by applications using the APIs of libgio. There is also FUSE support that allows applications not using GIO to access the GVfs filesystems. A cause of confusion is the fact that the file system abstraction used by the Linux kernel is also called the virtual file system (VFS) layer. This is however at a lower level. The GVfs model differs from e.g. GnomeVFS, which it replaces, in that file systems must be mounted before they are used. There is a master daemon (gvfsd) that handles coordinating mounts, and then each mount is (typically) in its own daemon process (although mounts can share daemon process). GVfs comes with a set of back-ends, including trash support, SFTP, FTP, WebDAV, SMB, and local data via Udev integration, OBEX, ...

Media Transfer Protocol
The Media Transfer Protocol (MTP) is an extension to the Picture Transfer Protocol (PTP) communications protocol that allows media files to be transferred automatically to and from portable devices. While technically "available" on Windows 10, in practice it is unreliable, especially when the external device's folders contain large numbers of items (e.g. photos or videos). Connections tend to drop and cannot be restored or restarted without rebooting both the external device's and the Windows 10 computer. Whereas PTP was designed for downloading photographs from digital cameras, Media Transfer Protocol allows the transfer of music files on digital audio players and media files on portable media players, as well as personal information on personal digital assistants. MTP is a key part of WMDRM10-PD, a digital rights management (DRM) service for the Windows Media platform. In 2011, it became the standard method to transfer files to and from Android. MTP is part of the "Windo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GnomeVFS
GnomeVFS (short for GNOME Virtual File System) was an abstraction layer of the GNOME platform for the reading, writing and execution of files. Before GNOME 2.22 GnomeVFS was primarily used by the appropriate versions of Nautilus file manager (renamed to GNOME Files) and other GNOME applications. A cause of confusion is the fact that the file system abstraction used by the Linux kernel is also called the virtual file system (VFS) layer. This is however at a lower level. Due to perceived shortcomings of GnomeVFS a replacement called GVfs was developed. GVfs is based on GIO and allows partitions to be mounted through FUSE. With the release of GNOME 2.22 in April 2008, GnomeVFS was declared deprecated in favor of GVfs GVfs (abbreviation for GNOME virtual file system) is GNOME's userspace virtual filesystem designed to work with the I/O abstraction of GIO, a library available in GLib since version 2.15.1.

GNOME Files
GNOME Files, formerly and internally known as Nautilus, is the official file manager for the GNOME desktop. GNOME Files, same as Nautilus, is a free and open-source software under the terms of the GNU Lesser General Public License. History Nautilus, the predecessor of the GNOME Files, was originally developed by Eazel and Andy Hertzfeld (founder of Eazel and a former Apple Inc., Apple engineer) in 1999. The name "Nautilus" was a play on words, evoking the exoskeleton, shell of a nautilus to represent an shell (computing), operating system shell. At the beginning of 2000, Richard Hestgray published the first screenshots of ''Nautilus'' 0.1 preview release: File:Nautilus 0.1 About.jpg, About dialog of version 0.1. File:Nautilus 0.1 Iconview.jpg, Main window of the same version, the very first one shown publicly. In December 2000, article under the title ''«Nautilus, GNOME’s new file manager»'' was published in the Linux Magazine. Nautilus replaced Midnight Commander in GNO ...

Virtual File System
A virtual file system (VFS) or virtual filesystem switch is an abstract layer on top of a more concrete file system. The purpose of a VFS is to allow client applications to access different types of concrete file systems in a uniform way. A VFS can, for example, be used to access local and network storage devices transparently without the client application noticing the difference. It can be used to bridge the differences in Windows, classic Mac OS/macOS and Unix filesystems, so that applications can access files on local file systems of those types without having to know what type of file system they are accessing. A VFS specifies an interface (or a "contract") between the kernel and a concrete file system. Therefore, it is easy to add support for new file system types to the kernel simply by fulfilling the contract. The terms of the contract might change incompatibly from release to release, which would require that concrete file system support be recompiled, and possibly m ...

WebDAV
WebDAV (Web Distributed Authoring and Versioning) is a set of extensions to the Hypertext Transfer Protocol (HTTP), which allows user agents to collaboratively author contents ''directly'' in an HTTP web server by providing facilities for concurrency control and namespace operations, thus allowing the Web to be viewed as a ''writeable, collaborative medium'' and not just a read-only medium. WebDAV is defined in by a working group of the Internet Engineering Task Force (IETF). The WebDAV protocol provides a framework for users to create, change and move documents on a server. The most important features include the maintenance of properties about an author or modification date, namespace management, collections, and overwrite protection. Maintenance of properties includes such things as the creation, removal, and querying of file information. Namespace management deals with the ability to copy and move web pages within a server's namespace. Collections deal with the creation ...

GIO (software)
GIO (Gnome Input/Output) is a library, designed to present programmers with a modern and usable interface to a virtual file system. It allows applications to access local and remote files with a single consistent API, which was designed "to overcome the shortcomings of GnomeVFS" and be "so good that developers prefer it over raw POSIX calls." GIO serves as low-level system library for the GNOME Shell/GNOME/GTK software stack and is being developed by The GNOME Project. It is maintained as a separate library, , but it is bundled with GLib. GIO is free and open-source software released under the GNU Lesser General Public License. Features * The abstract file system model of GIO consists of a number of interfaces and base classes for I/O and files. * There are a number of stream classes, similar to the input and output stream hierarchies that can be found in frameworks like Java. * There are interfaces related to applications and the types of files they handle. * There is a frame ...

Filesystem In Userspace
Filesystem in Userspace (FUSE) is a software interface for Unix and Unix-like computer operating systems that lets non-privileged users create their own file systems without editing kernel code. This is achieved by running file system code in user space while the FUSE module provides only a bridge to the actual kernel interfaces. FUSE is available for Linux, FreeBSD, OpenBSD, NetBSD (as puffs), OpenSolaris, Minix 3, macOS, MorphOS (as filesysbox.library), and Windows. FUSE is free software originally released under the terms of the GNU General Public License and the GNU Lesser General Public License. History The FUSE system was originally part of ''AVFS'' (''A Virtual Filesystem''), a filesystem implementation heavily influenced by the translator concept of the GNU Hurd. It superseded Linux Userland Filesystem, and provided a translational interface using in libfuse1. FUSE was originally released under the terms of the GNU General Public License and the GNU Lesser Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
GPhoto
gPhoto is a set of software applications and libraries for use in digital photography. gPhoto supports not just retrieving of images from camera devices, but also upload and remote controlled configuration and capture, depending on whether the camera supports those features. Released under the GNU Lesser General Public License, gPhoto is free software. Support gPhoto supports more than 2500 cameras as of June 2019. It is cross-platform, running under Linux, FreeBSD, NetBSD and other Unix-like operating systems. gPhoto has support for the Picture Transfer Protocol (PTP) and will also connect to devices that use the Media Transfer Protocol (MTP). Many cameras are not supported by gPhoto, but have support for the USB mass storage device class, which is well-supported under Linux. gPhoto intentionally does not implement support for USB mass storage cameras, as this is already implemented in-kernel. gPhoto supports camera tethering control, preview, viewfinder in PTP or c ...

Picture Transfer Protocol
Picture Transfer Protocol (PTP) is a protocol originally developed by the Photographic and Imaging Manufacturers Association (PIMA) (later known as the International Imaging Industry Association) to allow the transfer of images from digital cameras to computers and other peripheral devices without the need for additional device drivers. The protocol was standardized by the ISO in 2005. The current version of the standard is ISO 15740:2013. It is further standardized for USB by the USB Implementers Forum as the ''still image capture device class''. USB is the default network transport media for PTP devices. USB PTP is a common alternative to the USB mass-storage device class (USB MSC), as a digital camera connection protocol. Some cameras support both modes. Description PTP specifies a way of creating, transferring and manipulating ''objects'' which are typically photographic images such as a JPEG file. While it is common to think of the objects that PTP handle as files, they ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daemon (computing)
In computing, a daemon is a program that runs as a background process, rather than being under the direct control of an interactive user. Customary convention is to name a daemon process with the letter ''d'' as a suffix to indicate that it's a daemon. For example, is a daemon that implements system logging facility, and is a daemon that serves incoming SSH connections. Even though the concept can apply to many computing systems, the term ''daemon'' is used almost exclusively in the context of Unix-based systems. In other contexts, different terms are used for the same concept. Systems often start daemons at boot time that will respond to network requests, hardware activity, or other programs by performing some task. Daemons such as cron may also perform defined tasks at scheduled times. Terminology In the context of computing, the word is generally pronounced either as or . The term was coined by the programmers at MIT's Project MAC. According to Fernando J. Cor ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
D-Bus
D-Bus (short for "Desktop Bus") is a message-oriented middleware mechanism that allows communication between multiple Process (computing), processes running concurrently on the same machine. D-Bus was developed as part of the freedesktop.org project, initiated by GNOME developer Havoc Pennington to standardize services provided by Linux desktop environments such as GNOME and KDE. The freedesktop.org project also developed a free and open-source software library called libdbus, as a reference implementation of the specification. This library is not D-Bus itself, as other implementations of the D-Bus specification also exist, such as GDBus (GNOME), QtDBus (Qt (software), Qt/KDE), dbus-java and sd-bus (part of systemd). Overview D-Bus is an inter-process communication (IPC) mechanism initially designed to replace the software component communications systems CORBA and Desktop communication protocol, DCOP, used by the GNOME and KDE Linux desktop environments respectively.
