I wrote about Sequoiaview in depth in SequoiaView Homepage, made some research notes in “cushion treemap” delphi – Google Search and touched it slightly in A choco install list.
I never heard back from my request for Sequoiaview source code, and given ever increasing local storage media sizes, the speed of it now has become an issue, so I started looking to see if more alternatives have appeared and what sets them apart.
TL;DR
- There is the open source WinDirStat that runs as non-admin and is about as slow as Sequoiaview
- There is the closed source but free for personal use WizTree that requires admin elevation and is much faster than Sequoiaview and WinDirStat
Neither of them allow for a view that is cushion treemap only.
The reason that WizTree is fast is that it directly uses the NTFS MFT (Master File Table) to read the information from. This requires elevated permissions.
This is the same mechanism used by the Everything search tool, but unlike Everything, WizTree:
On the TODO list is to write more about the origin of “grief doesn’t shrink we grow around it”. For now, this is good enough:
