This tool is used to visualize disk usage in a simply and nice graph.


  • Indexing filesystem very fast
  • Interact with graph with click and double click to navigate in the directories tree.


This tool is composed by two parts: duc indexer and duc viewer. The first one is launched every day and it indexes the / directory and it creates a file that is loaded by duc viewer to show graph.

In the graph are showed only directories over certain size, in particularly this size is 10MB as you can see in file /etc/e-smith/events/actions/nethserver-duc-index.


By default, duc will skip directories on different file systems. To change this behavior and include all filesystems execute:

config setprop duc OneFileSystem disabled
