The path to root option dialog is displayed after clicking the Show path to GC root toolbar button in the reference graph of the heap walker.

| The path to root analysis can calculate: a single root Only a single garbage collector root will be found. When searching for a memory leak, this option is often appropriate since any path to a garbage collector root will prevent the instance from being garbage collected. up to a certain number of roots A specified maximum number of roots will be found and displayed. If a single root is not sufficient, try displaying one root more at a time until you get a useful result. all roots All paths to garbage collector roots will be found and displayed. This analysis takes much longer than the single root option and can us a lot of memory. After completing the dialog with the [Ok] button, the analysis will be calculated and the result will be shown in the reference graph. With the [Cancel] button, the path to root option dialog is closed and no analysis is performed.
