You operate a little cleaner than I do- there are invariably things that end up in /usr/local/bin..

Still, thanks for the process you use.

My wsl is pretty long lived now, through quite a few ubuntu upgrades and installations of stuff that I probably no longer need.

you can try doing fstrim + Optimize-VMD first . i've found it is good up to 20% savings. On my last run my 75 gb wsl disk saved about 15gb. But wiping and re-installing trimmed about 60 gb
