That’s not necessarily a bad thing. I still use it and it does exactly what I want it to do - help me figure out what’s using up all of the space on my disk. It used to usually be media files. These days it’s usually Windows.
I used it back in days of 98 and XP. There were things they were going to develop. They were related to search I think. Don't remember. They remained only partially implemented.
SpaceSniffer on the other hand don't have that many features but it's very fast. If you are cleaning up files, you can see the size of boxes getting smaller in realtime as files being deleted.
