Disk Usage Analyzer (Baobab)
Close matchFreeCalled Disk Usage Analyzer and already installed. Same ranked folder list, no PDF reports.
Does TreeSize run on Linux?
Verdict: No
No. TreeSize is a Windows desktop tool and JAM Software offers no Linux version, but the disk usage tool that comes with Linux answers the same question about where your space has gone.
JAM Software describes TreeSize Free as a Windows desktop tool for personal, non-commercial use, and notes it is not usable on Windows Servers. Linux is not offered in any edition.
Disk Usage Analyzer is the replacement and it is already on your system. It scans a folder, a whole drive or an external disk and ranks what it finds by size, with a coloured map alongside the list. That covers what most people used TreeSize Free for, which is finding the one folder that ate 200GB.
Two things are weaker. TreeSize can generate a PDF report of a scan and the Linux tool cannot, and TreeSize's paid editions do scheduled scans and network shares that have no free equivalent. If you used it in a work setting for those, that gap is real.
For a home user it is not a gap at all. On KDE systems the equivalent is called Filelight and looks even closer to what you are used to.

This doesn't have to stop you
One stubborn program doesn't have to decide the whole question. You can keep Windows on the same PC and restart into it only when you need TreeSize. Everything else you do can move.
