The client–server model is a distributed application structure that partitions tasks or workloads between the providers of a resource or service, called servers, and service requesters, called clients. Often clients and servers communicate over a computer network on separate hardware, but both client and server may be on the same device. A server host runs one or more server programs, which share their resources with clients. A client usually does not share any of its resources, but it requests content or service from a server. Clients, therefore, initiate communication sessions with servers, which await incoming requests. Examples of computer applications that use the client–server model are email, network printing, and the World Wide Web.
Uploading refers to transmitting data from one computer system to another through means of a network. Common methods of uploading include: uploading via web browsers, FTP clients, and terminals (SCP/SFTP). Uploading can be used in the context of clients that send files to a central server. While uploading can also be defined in the context of sending files between distributed clients, such as with a peer-to-peer (P2P) file-sharing protocol like BitTorrent, the term file sharing is more often used in this case. Moving files within a computer system, as opposed to over a network, is called file copying.
The File Transfer Protocol (FTP) is a standard communication protocol used for the transfer of computer files from a server to a client on a computer network. FTP is built on a client–server model architecture using separate control and data connections between the client and the server. FTP users may authenticate themselves with a plain-text sign-in protocol, normally in the form of a username and password, but can connect anonymously if the server is configured to allow it. For secure transmission that protects the username and password, and encrypts the content, FTP is often secured with SSL/TLS (FTPS) or replaced with SSH File Transfer Protocol (SFTP).
Extensible Messaging and Presence Protocol is an open communication protocol designed for instant messaging (IM), presence information, and contact list maintenance. Based on XML, it enables the near-real-time exchange of structured data between two or more network entities. Designed to be extensible, the protocol offers a multitude of applications beyond traditional IM in the broader realm of message-oriented middleware, including signalling for VoIP, video, file transfer, gaming and other uses.
In computing, the SSH File Transfer Protocol is a network protocol that provides file access, file transfer, and file management over any reliable data stream. It was designed by the Internet Engineering Task Force (IETF) as an extension of the Secure Shell protocol (SSH) version 2.0 to provide secure file transfer capabilities, and is seen as a replacement of File Transfer Protocol (FTP) due to superior security. The IETF Internet Draft states that, even though this protocol is described in the context of the SSH-2 protocol, it could be used in a number of different applications, such as secure file transfer over Transport Layer Security (TLS) and transfer of management information in VPN applications.
Network-attached storage (NAS) is a file-level computer data storage server connected to a computer network providing data access to a heterogeneous group of clients. The term "NAS" can refer to both the technology and systems involved, or a specialized device built for such functionality.
cURL is a computer software project providing a library (libcurl) and command-line tool (curl) for transferring data using various network protocols. The name stands for "Client for URL".
RealVNC is a company that provides remote access software. Their VNC Connect software consists of a server and client application, which exchange data over the RFB protocol to allow the Viewer to control the Server's screen remotely. The application is used, for example, by IT support engineers to provide helpdesk services to remote users.
FileZilla is a free and open-source, cross-platform FTP application, consisting of FileZilla Client and FileZilla Server. Clients are available for Windows, Linux, and macOS. Both server and client support FTP and FTPS, while the client can in addition connect to SFTP servers. FileZilla's source code is hosted on SourceForge.
gFTP is a free and open-source multithreaded File Transfer Protocol client program. It is most used on Unix-like systems such as Linux, macOS, and Sony PlayStation 3. It includes both a graphical user interface (GUI), which utilizes the GTK+ graphical toolkit, and a command-line interface. gFTP is released under the terms of the GPL and has been translated into 45 languages.
FTPS is an extension to the commonly used File Transfer Protocol (FTP) that adds support for the Transport Layer Security (TLS) and, formerly, the Secure Sockets Layer cryptographic protocols.
File Service Protocol (FSP) is a UDP-based replacement for the File Transfer Protocol, designed for anonymous access with lower hardware and network requirements than FTP. In particular, because it uses UDP, it avoids the problems that many FTP servers have had with requiring a separate process for each client, and because it is built to use an unreliable protocol, it can more easily handle resuming a transfer after a network failure.
WinSCP is a file manager, SSH File Transfer Protocol (SFTP), File Transfer Protocol (FTP), WebDAV, Amazon S3, and secure copy protocol (SCP) client for Microsoft Windows. The WinSCP project has released its source code on GitHub under an open source license, while the program itself is distributed as proprietary freeware.
Transmit is a file transfer client program for macOS developed by Panic Inc. Transmit is trialware; after a seven-day trial period, the product can only be used for seven-minute sessions until it is purchased. Transmit was originally built as an FTP client and now supports a number of protocols including SFTP and WebDAV and cloud services including Google Drive and Dropbox.
WinSock File Transfer Protocol, or WS_FTP, is a secure file transfer software package produced by Ipswitch, Inc. Ipswitch is a Massachusetts-based software producer established in 1991 that focuses on networking and file sharing. WS_FTP consists of an FTP server and an FTP client and has over 40 million users worldwide.
CrushFTP is a proprietary multi-protocol, multi-platform file transfer server originally developed in 1999. CrushFTP is shareware with a tiered pricing model. It is targeted at home users on up to enterprise users.
ExpanDrive is a network filesystem client for MacOS, Microsoft Windows and Linux that facilitates mapping of local volume to many different types of cloud storage. When a server is mounted with ExpanDrive any program can read, write, and manage remote files as if they were stored locally. This is different from most File Transfer Clients because it is integrated into all applications on the operating system. It also does not require a file to be downloaded to access portions of the content. ExpanDrive is commercial software, at a cost of $49.95 per license. A 7-day, unrestricted demo is available for evaluation.
GlobalScape, Inc. (AMEX:GSB) is a software developer headquartered in San Antonio, Texas, US.
WebDrive is a drive mapping utility that supports accessing remote file servers using open FTP, FTPS, SFTP, and WebDAV protocols, and proprietary or vendor-specific protocols. It can be run as a Windows service and supports automatic mounting on system startup.
Commander One is a dual-pane file manager designed for macOS. Developed by Electronic Team, Inc., the software is created entirely in Swift and aims to provide users with a tool to navigate, manage, and manipulate files and folders on their Mac computers. The application offers a wide range of features for both casual and professional users.
