AntFlow builds upon Apache Ant to provide a new approach to simplifying system automation that uses pipelines of hot folders chained together to perform a given task. Using XML, it associates an automated task such as data transfer, encryption, or XML processing with a directory on the local system. Whenever a file is copied or written into the hot folder, the associated task is executed and the file is moved to the next hot folder in the pipeline for further processing.
ADTPro transfers disks to and from Apple II and Apple /// computers and the modern world using any of these communications methods: serial/USB, UDP via the Uthernet or LANceGS Ethernet cards, or audio via the Apple's cassette ports. ADTPro has comprehensive bootstrapping support for otherwise diskless Apple IIs. The home page includes extensive tutorials for getting started.
ArchView can open archive files online without downloading the whole archive, just like normal Web pages. It is very fast since it just fetches a small portion of the archive file from the server. It supports RAR and ZIP formats, and HTTP, FTP, and file: protocols. It can present XUL or HTML interface.
Archery is a script to extract archives intelligently. It always extracts to a single directory or file, whether the archive was prepared that way or not, so you don't have to worry about it making a mess where you are working. It supports external extractors for .arj, .cab, .tar, .ace, .lha, .rar, .7z, and cpio formats.
Archive is a fully drag-and-drop multi-format archiver. Drag a directory onto it to create an archive. Drag an archive onto it to extract to a directory. It can also compress and decompress streams (for example, you could drag a .gz file onto Archive and from Archive into your text editor).
Areca is a file backup system that supports data compression (zip / zip64 format) and encryption, incremental backups, FTP/SFTP file transfer, delta storage mode, and many other features. It includes a transaction mechanism, which guarantees the integrity of your backups. Two user interfaces are available: a command-line interface (useful for backup automation) and a graphical user interface (useful for backup administration).
Arnie is a simple system for making incremental backups to remote files. Backup archives can be optionally encrypted for untrusted online remote storage. It only requires Python 2.4 and provides two scripts: archive and restore. The system is extremely simple to set up, and a comprehensive test suite is provided.
