KDirStat is a graphical disk usage utility, very much like the Unix "du" command.
KDirStat project displays a directory tree both in classical tree format (like Konqueror, but with accumulated tree sizes, shown as MB / GB and as percentage bars) and in "treemap" format like SequoiaView.
In addition to that, KDirStat provides cleanup facilities to reclaim disk space - both predefined and customizable.
Here are some key features of "KDirStat":
· Graphical and numeric display of used disk space
· Files kept apart from directories in separate items to prevent cluttering the display
· All numbers displayed human readable - e.g., 34.4 MB instead of 36116381 Bytes
· Different colors in the directory tree display to keep the different tree levels visually apart
· Display of latest change time within an entire directory tree - you can easily see what object was changed last and when.
· Treemap as alternate (auxiliary) view of a directory tree
· Easily find large in a directory tree: You see the entire tree at once. Large rectangles are large files - you can see them even if they are hidden somewhere deep within the tree.
· Treemap view slaved to the tree (list) view: Click on a file in the treemap, and it is selected in the tree view - and vice versa.
· Treemap tiles are colored by file type - all images in cyan, all audio tracks (MP3 etc.) in yellow, executables in magenta etc.; you can see from the color what a treemap rectangle is.
· Many treemap variants available:
· Plain treemap
· Squarified treemap (no thin elongated rectangles)
· Cushion treemap
· Colored treemap
· All combinations of the above
· Fast implementation: Treemap built in fractions of a second (on quite ordinary machines: Athlon-550 class)
· Treemap subwindow can be resized as the user prefers
· Treemap can be switched off with a single keypress (F9)
· Context menu with cleanup actions etc.
· Zoom the treemap in/out treemap with double click (left/right)
· Many treemap configuration options
· Stays on one file system by default - reads mounted file systems only on request.
· You don't care about a mounted /usr file system if the root file system is full and you need to find out why in a hurry, nor do you want to scan everybody's home directory on the NFS server when your local disk is full.
· Network transparency: Scan FTP or Samba directories - or whatever else protocols KDE support.
· PacMan animation while directories are being read. OK, this is not exactly essential, but it's fun.
· Predefined cleanup actions: Easily delete a file or a directory tree, move it to the KDE trash bin, compress it to a .tar.bz2 archive or simply open a shell or a Konqueror window there.
· User-defined cleanup actions: Add your own cleanup commands or edit the existing ones.
· "Send mail to owner" report facility: Send a mail requesting the owner of a large directory tree to please clean up unused files.
· Feedback mail facility: Rate the program and tell the authors your opinion about it.
What's New in 2.4.4 Release:
· Sparse files and hard links are now properly supported.
What's New in 2.5.2 Release:
· Can now read and write directory contents from cache files generated by (supplied) Perl script, e.g. in cron job over night
