Free disk defragmenter software for linux

Disk Manager project is a simple filesystem configurator that allow you to:
- Automaticly detect new partitions at startup.
- Fully manage configuration of filesystem.
- Enable/disable write support for NTFS (need ntfs-3g installed).

xdiskusage is a user-friendly program to show you what is using up all your disk space.

It is based on the design of xdu written by Phillip C. Dykstra.

Changes have been made so it runs "du" for you, and can display the free space left on the disk, and produce a PostScript version of the display.

The arrow keys may be used to move the selected directory (shown with a red box) around. There is a pop-up menu (use the right mouse button) with other options for changing the display, you can hide nodes, make that node the "root", change the sort order, etc.

Apple Disk Transfer ProDOS (or ADTPro for short) transfers diskettes and logical disk images between Apple ][-era computers and the modern world. If youre familiar with the original ADT, ADTPro extends ADTs reach by working with more logical disk formats, drive types, communications devices, and host operating systems.
Main features:
- Compatibility with any device ProDOS can read
- Compatibility with any Apple ][ (or clone) computer with 64k memory
- Compatibility with many logical disk image formats: .DSK, .PO, .NIB, 2IMG
- Server compatibility with original ADT client program
- Server compatibility with Windows, Mac OSX, Linux, and probably Solaris
- Ability to bootstrap an Apple ][ from bare metal over serial or cassette ports
- Ability to send floppies in "batch" mode without having to name each one
Server
The server program runs on a computer capable of running Java. Depending on how you want to connect to your Apple, you might also need a serial port and cables, an Uthernet card for your apple, or a couple of audio patch cables. The server offers a compact user interface that shows what communications are taking place between the host and the Apple ][.
The servers primary role is to send and receive disk images as requested from the client. But if you have recently acquired an Apple and a disk drive, and you have no software for it - youre in a bit of a tricky situation if you want to move software from the Internet all the way to your shiny new Apple. ADTPros server can help get you get bootstrapped.
Client
The client side runs on the Apple ][. It handles most of the user interaction. When choosing disks/volumes to transfer, anything that ProDOS can see is fair game. Transferring data occurs with a 20k buffer on the Apple, so all transfers are broken up into 20k chunks. A progress indicator shows how far it is into the current chunk, as well as a running count of the total progress.
Enhancements:
- This release has been enhanced with Jean-Marc Boutillon (Deckard)s FASTDSK fast Disk II reading routines.
- This results in a speed boost of 25%-33% for Disk II to host transfers.
- Bootstrapping operations have been reduced, as there is no longer a dependency on ProDOS BASIC.

cfgstoragemaker remotely generates an MRTG config file in order to graph all storage devices (disk, memory, and swap) of one or more specific host(s) via SNMP.
