Intent

Use the 80:20 rule to draw the user's attention to the few subdirectories or files that consume most disk space on that level: Highlight those items, if it makes sense.

Research what approach is most useful to identify such dominant items:

• Average size and standard deviation?
• Median, quartiles and interquartile distance?
• Something else?
