This might be worth a PSA - if you use #VSCode via Snap, every file you delete inside VSCode is not actually getting deleted. It goes to a "Trash" folder in the ~/snap/code/current/Trash and never (ever) gets deleted. Last year I found I had 44 GB in undeleted files, in that GitHub issue this is happening to a lot of people.

There's been an open bug ticket for over a year: https://github.com/microsoft/vscode/issues/233649#issuecomment-3830929735
