Krypt is a simple application that sits in the system tray and provides easy access to the list of volumes encrypted with LUKS. It is possible to quickly decrypt, encrypt back, mount, and umount such devices. It also monitors HAL activity, and responds by showing a pop-up with password prompt. When the password is provided, KDE's media manager kicks in and does its job. Passwords for volumes can be stored either in a configuration file or in KDE Wallet.
synDirectory is used to retrieve and sort the current work directory list of of files. It opens the current directory and retrieves the list of files and sub-directories into separate arrays. Since it may be listing the directory where this package was installed, the package files are excluded from the listing. The arrays with the files and directories may be sorted by name, file size, file type, or last modified date. The package comes with a configuration file to help the user customize the output further. It is also possible to skin the output via CSS.
Duplicate Files Searcher is an application for finding and deleting duplicate files on your computer. It can also be used to calculate MD5 and SHA hashes. It has features such as manual files selection (giving the user full control over files to be deleted), byte for byte file comparison, file preview, several file comparison methods, and more.
iloog is a Gentoo-based live CD targeted mainly at students and scientists. It features UnionFS filesystem support that enables you to write everywhere on the LiveCD and install extra packages, a graphical X environment through the Fluxbox window manager, many programming editors and IDEs, and a plethora of scientific applications, including Octave, Namd, Merlin, and full (La)TeX support.
Tagsistant is a semantic filesystem for Linux and BSD kernels. It uses directories as tags and allows file tagging by simply putting files inside desired tag directories. The path you are walking by is your query, e.g. tagsistant/tag1/AND/tag2/OR/tag3/AND/tag2/. Being a low level interface, a filesystem can be instantly used by shell users, file managers, or CGI. A plug-in architecture is under development to add autotagging functionality for common files like .mp3, .ogg, .jpeg, .html, and .xml. A transparent ontology engine is also under development to allow users create a relationship schema between directories.
