SpaceSniffer 找出強佔硬碟空間的兇手

Brief product description

Latest release is 1.1.4.0

SpaceSniffer is a freeWare (donations are welcome) and portable tool application that lets you understand how folders and files are structured on your disks. By using a Treemap visualization layout, you have immediate perception of where big folders and files are placed on your devices.Treemap concept was invented by Prof. Ben Shneiderman, who kindly permitted the use of his concept into this tool.

Start a scan process and see the overall situation. Bigger are the elements on the view, bigger are folders and files on your disk. You need more detail on a big folder? Just single click on it. The selected element will be detailed with its content.

Need more and more detail? Keep selecting elements and they’ll discover their secrets to you. Need a larger view of a small folder? Then double click on it, and it’ll zoom to the full extent of the view.

If you need to understand why no more free space is left on media, keep following bigger elements. Maybe you want to focus only on particular file types… ok. Just type the file type on the filter field (example: *.jpg) and press enter. The view will react and show you only JPEG files.
Want to exclude files? Then type a starting pipe before the filter (example: |*.jpg) and press enter. The view will show everything but JPEG files.

If you want to keep track of examined files you can tag them. Four colors are available. Just hover the mouse on a file and press CTRL+1 to tag it red. There are keys also for yellow, green and blue tagging. Use them as you wish. You can also filter on tags (example: :red will show only red tagges files, :all will show all tagged files and so on). You can also exclude tagged files (example: |:red will exclude all red tagged files)

Want to know if you have old files? Type the condition in the filter field (example: >2years) and the view will react accordingly.

You can also filter on file sizefile date and combine all filters
(example: *.jpg;>1mb;<3months;|:yellow)

Once you have your result, you can produce a textual report by using the embedded Export Module. You can even customize the report layout to match your needs.

Please have a look at features. Download here. Support here. Enjoy everywhere!

Windows Directory Statistics 抓出佔硬碟空間的兇手

WinDirStat is a disk usage statistics viewer and cleanup tool for various versions of Microsoft Windows.
Note: if you are looking for an alternative for Linux, you are looking for KDirStat (apt-get install kdirstat on Debian-derivatives) and for MacOS X it would be Disk Inventory X or GrandPerspective.

Please visit the WinDirStat blog for more up-to-date information about the program.

On start up, it reads the whole directory tree once and then presents it in three useful views:

  • The directory list, which resembles the tree view of the Windows Explorer but is sorted by file/subtree size,
  • The treemap, which shows the whole contents of the directory tree straight away,
  • The extension list, which serves as a legend and shows statistics about the file types.

Screenshot

The treemap represents each file as a colored rectangle, the area of which is proportional to the file’s size. The rectangles are arranged in such a way, that directories again make up rectangles, which contain all their files and subdirectories. So their area is proportional to the size of the subtrees. The color of a rectangle indicates the type of the file, as shown in the extension list. The cushion shading additionally brings out the directory structure.

Howto: Display All Hard Disk of Size on Machine

Just use fdisk to list all disk state and grep prefix Disk string line to show.

# fdisk -l 2> /dev/null | grep ^Disk | grep -v identifier
