ComfyUI disk usage: checkpoints, outputs and temp

ComfyUI disk usage: checkpoints, outputs and temp — what's safe

ComfyUI's appetite = models (5–24 GB each) + outputs (every generation saved) + temp frames.

Typical layout

Dir	Content	Safe?
`models/checkpoints/`, `models/loras/`	SD/SDXL/Flux weights	Keep what you use
`output/`	every generation image/video	Archive or delete
`temp/`	preview frames	Yes, always
`input/`	uploaded sources	Your call

du -sh ComfyUI/models/* ComfyUI/output | sort -h
find ComfyUI/temp -type f -delete
find ComfyUI/output -mtime +30 -name '*.png' -delete

Workflows reference deleted models?
They'll error on load — move models you still use in workflows.
