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.
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.
The following tables compare general and technical information for a number of File Transfer Protocol (FTP) clients. Unless otherwise specified in footnotes, comparisons are based on the stable versions without any add-ons, extensions, or external programs.
WinSCP is a free and open-source SSH File Transfer Protocol (SFTP), File Transfer Protocol (FTP), WebDAV, Amazon S3, and secure copy protocol (SCP) client for Microsoft Windows. Its main function is secure file transfer between a local computer and a remote server. Beyond this, WinSCP offers basic file manager and file synchronization functionality. For secure transfers, it uses the Secure Shell protocol (SSH) and supports the SCP protocol in addition to SFTP.
An SSH client is a software program which uses the secure shell protocol to connect to a remote computer. This article compares a selection of notable clients.
Walnut Creek CDROM Inc. was an early provider of freeware, shareware, and free software on CD-ROMs. The company was founded in by Bob Bruce in Walnut Creek, California, in August 1991. It was one of the first commercial distributors of free software on CD-ROMs. The company produced hundreds of titles on CD-ROMs, and ran the busiest FTP site on the Internet, ftp.cdrom.com, for many years.
Simtel was an important long-running archive of freeware and shareware for various operating systems.
Pure-FTPd is a free FTP Server with a strong focus on software security. It can be compiled and run on a variety of Unix-like computer operating systems including Linux, OpenBSD, NetBSD, FreeBSD, DragonFly BSD, Solaris, Tru64, Darwin, Irix and HP-UX. It has also been ported to Android.
Metalink is an extensible metadata file format that describes one or more computer files available for download. It specifies files appropriate for the user's language and operating system; facilitates file verification and recovery from data corruption; and lists alternate download sources.
TrueNAS is the branding for a range of free and open-source network-attached storage (NAS) operating systems produced by iXsystems, and based on FreeBSD and Linux, using the OpenZFS file system. It is licensed under the terms of the BSD License and runs on commodity x86-64 hardware.
The Berkeley Software Distribution or Berkeley Standard Distribution (BSD) is a discontinued operating system based on Research Unix, developed and distributed by the Computer Systems Research Group (CSRG) at the University of California, Berkeley. The term "BSD" commonly refers to its open-source descendants, including FreeBSD, OpenBSD, NetBSD, and DragonFly BSD.
An SSH server is a software program which uses the Secure Shell protocol to accept connections from remote computers. SFTP/SCP file transfers and remote terminal connections are popular use cases for an SSH server.
OpenSSH is a suite of secure networking utilities based on the Secure Shell (SSH) protocol, which provides a secure channel over an unsecured network in a client–server architecture.
ProFTPD is an FTP server. ProFTPD is Free and open-source software, compatible with Unix-like systems and Microsoft Windows . Along with vsftpd and Pure-FTPd, ProFTPD is among the most popular FTP servers in Unix-like environments today. Compared to those, which focus e.g. on simplicity, speed or security, ProFTPD's primary design goal is to be a highly feature rich FTP server, exposing a large amount of configuration options to the user.
