During the lifetime of a typical computer, many folders are static in their contents. For example, a program like Matlab, loaded with some toolboxes, is installed once and seldom changes ever after. It takes a large amount of disk space, but more importantly, it contains thousands of small files.
These folders substantially slow down the WinDirStat file tree scan.
The utility's interface allows to scan subtrees. But can you exclude a subtree while scanning its parent tree?
These folders substantially slow down the WinDirStat file tree scan.
Instead of attempting to persuade an extremely outdated utility to work efficiently, I recommend switching to a superior free tool that benefits from ongoing developer support: TreeSize.
Based on my recent experience with WinDirStat, it's about 10x slower than TreeSize!
WizTree (https://diskanalyzer.com/) is also way faster so you wouldn't have that problem
SpaceSniffer (http://www.uderzo.it/main_products/space_sniffer/) supports filters, which apart from (I guess) avoiding to scan that directory, also avoids showing it on the treemap
