eXtplorer is a Web-based file manager. It allows you to copy and move files and directories by drag and drop, display a dynamic directory tree with on-demand loading of subdirectories, create and edit files with syntax highlighting, access files either directly or through FTP to overcome permission and file ownership issues, upload and download files, create and extract archives, and set up users with different permission levels. It can be used standalone or as a component for Joomla!.
Alaya is a primitive chrooting Web server with basic WebDAV support. It can serve HTTPS and HTTP, and can authenticate using PAM, /etc/shadow, /etc/passwd, or using its own authentication files that allow for 'native' users that only have access to alaya content. It's intended to be a simple method of sharing content over WebDAV, and though it can be configured with a config file, it's easy to configure by command-line switches alone. Alaya always chroots to ensure that malicious users can't use '..' within a URL to access unintended documents, and that users can't accidentally leave documents in places outside of the chroot. It has a 'ChHome' mode that chroots users into their home directory and serves content from there. It supports .cgi scripts out of a trusted path (so not from within the chrooted WebDAV share) and read-only shared directories that are outside of the chroot (allowing access to shared content when in ChHome mode).
Dove is an application that facilitates the distribution of documents to a variety of destination types such as email, local files, FTP, FTPS, SFTP, TFTP, Samba servers, Windows network shared drives, and WebDAV servers. Being an abstraction layer over previously enumerated protocols, it allows sending of documents to email or to a WebDAV server with equal ease.
exJello is a JavaMail provider that connects to a Microsoft Exchange server (actually, it uses the WebDAV interface exposed by Outlook Web Access). It is designed as a drop-in replacement for the standard POP3 and SMTP providers. This allows you to send and receive messages through your Exchange server in situations where a POP3/SMTP interface is not available (through a restrictive firewall, for example, or if your administrator simply does not provide a POP3 or SMTP gateway).
Sardine is a next generation WebDAV client for Java. It is intended to be simple to use and does not implement the full WebDAV client spec. Instead, the goal is to provide methods for most use case scenarios when working with a WebDAV server. The code needs to run as fast as possible and use the latest released Apache HttpComponents.
SabreDAV allows you to easily integrate your existing Web application with WebDAV. It supports most of the common clients, including the Mac OS X Finder, the Windows XP/Vista Explorer, DavFS2, Cadaver, NetDrive, and WebDrive. It supports class 1, 2, and 3 WebDAV servers. It implements RFC2518 and revisions from RFC4918. It also implements RFC2617 (Basic/Digest auth).
Duplicati is a backup system and an implementation of Duplicity. Duplicati enables you to set up and monitor backups on Windows or Linux. Duplicati is based on the Linux-only Duplicity backup system. Duplicati has a very user friendly interface that allows you to configure and monitor your backups. It supports backing up to a variety of destinations, such as a network folder, a USB disk, a remote FTP server, a remote SSH server, Amazon S3 storage, or a WebDAV enabled server. All backups can be encrypted and are digtally signed, so that no other person can read or tamper with the backed up data.
