STORAGE VISUALIZATION / FIELD GUIDE 11

Visual Disk Browser

Turn rectangles, rings, and lists into a precise explanation of the storage you actually inspected.

Learn the chart grammar

A visual disk browser encodes a hierarchy into shapes. Read the measurement, legend, and selected root before interpreting the picture. The WinDirStat project describes a treemap with file size represented by area and file type by color. Treat that as a documented example, not a guarantee that all tools use identical conventions.

Use the overview to find the next question

Select a prominent branch, recover its exact path, and inspect the related items in a readable listing. The map can help orient an investigation, but it does not establish whether the material is active, reproducible, or safe to remove. Keep measured size, operational purpose, and approval as separate fields in your review.

Compare equivalent observations

Use a known sample and the same scope when comparing views. Record the measurement label, access gaps, and observation time. Do not add a parent’s total to its descendants. If a report is partial, keep that label attached to any exported image or written summary.

Build a map somebody else can use

Pair a highlighted view with short path-based findings. Explain the relevant branch in words so the report remains useful without color or interactivity. Redact sensitive names before sharing outside the authorized group. Repeat the same scoped observation after an approved change instead of judging the outcome from visual impression alone.

Questions worth asking

Does the largest rectangle identify an unnecessary file?

No. It identifies a measured item within a particular chart. Purpose, ownership, and safe handling require separate evidence.

Should I choose a treemap or a ring view?

Test the question you need answered with a known sample. Compare orientation, path recovery, labels, and keyboard usability instead of assuming one chart is best for every workflow.
