FolderCleaner🐶

Run an agent loop enough times and your output/temp folder fills up with junk from every past iteration. FolderCleaner is the housekeeping node for that - point it at a folder, tell it what kind of file to delete, and it clears the folder out. It lives in this pack's "workflow" category alongside its batch/iterator nodes (json_iterator, json_writing), which is the tell for what it's actually for: clearing a working directory before or between runs of a loop, so old files don't get picked up by mistake on the next pass.

Read this before you run it: it deletes files, and there's no undo. Double-check folder_path before you execute the node, especially the first time - point it at the wrong folder and you've just deleted whatever was in it, not just your intended temp files.

How it works

It's a straightforward delete-by-extension operation, not a smart cleanup - you give it a folder and a category, it removes matching files from that folder.

The inputs and outputs that matter

• folder_path - the folder to clean. No default, so you have to set this deliberately.
• file_type - what to delete: image, audio, video, all_files, or all. The schema doesn't spell out the exact difference between all_files and all (subfolders included vs. not, is a reasonable guess but untested here) - if that distinction matters for your setup, test on a throwaway folder first rather than trusting it on data you care about.
• any (required, wildcard type) and the matching any output - this isn't real data flowing through the node, it's a pure ordering trigger. Wiring something into any and taking the same wildcard back out is how ComfyUI graphs force execution order between nodes that don't otherwise share data - it guarantees FolderCleaner runs before whatever consumes its output, without needing a real dependency between them.
• is_enable - standard bypass toggle.

How to install it

Via ComfyUI Manager: search comfyui_LLM_party, install, restart. Manually:

cd ComfyUI/custom_nodes
git clone https://github.com/heshengtao/comfyui_LLM_party.git

Then pip install -r requirements.txt from inside the pack folder using ComfyUI's own Python, and restart. No models or API keys needed for this specific node - it's pure filesystem plumbing.

Common issues & troubleshooting

It deleted more than you expected. Almost always a wrong folder_path or the wrong file_type choice (picking all when you meant one category). There's no recovery built into the node - if this is a real risk in your setup, point it at a dedicated scratch folder you never store anything valuable in, rather than a shared output directory.

Running on a hosted/cloud executor and the folder doesn't behave the way it does locally. The path has to exist on whatever filesystem the node actually executes on. On a cloud worker that filesystem is the container's own ephemeral storage, not your local machine - make sure folder_path points somewhere inside the run's own working area, not a path that only made sense on your desktop.

Nothing gets deleted at all. Check is_enable is actually on, and that folder_path doesn't have a typo or trailing slash mismatch that's silently pointing at an empty or nonexistent directory.
