Just downloaded WizTree (not a sponsor) from https://wiztreefree.com/

It seems to do what it says on the tin which is the ability to quickly view the size of all files and folders visually.

I've given a donation which turns off the donation messages seen in exports with the free version. I feel better about donating because I work on the principal that a worker is worth their wages. And software developers need to eat and good software is well worth it

I have a feeling now I'm back in the Windows world that I will be using it regularly
