TS Files Downloader

You get a workflow from a friend - or from a reddit share - and it needs four models you don't have, from three different sources, in three different folders. Downloading them by hand is a chore, and a shared workflow that can't self-install is a workflow that dies on arrival. TS Files Downloader is the node that fixes that: give it a list of URL <space> target_path lines and it downloads them sequentially, with resume, mirror fallback, size/SHA verification, and optional auto-unzip. Handy for one-shot pulling all the assets a workflow needs.

The killer feature is the button: "Get models from workflow." It walks the open graph - including inside subgraphs - and collects every model every loader needs, reading the {name, url, directory} metadata ComfyUI stamps onto each loader. You get a report first; Append adds only what's missing, Replace list starts over.

How it works

The format is one download per line, URL <space> target_path. Target can be absolute, a models/... path, or a registered folder name (checkpoints, loras, vae - whatever ComfyUI already knows). Lines starting with # are ignored. It talks HTTP directly (via requests, a pack requirement), streams in chunks (chunk_size_kb, default 4096), and:

• Resumes interrupted downloads - a partial file is kept as .part, so the next run continues instead of restarting.
• Verifies - verify_size checks each finished file against the server-reported size or HF SHA256, and re-downloads/resumes on mismatch.
• Swaps HF mirrors - hf_domain lists mirror domains (default huggingface.co, hf-mirror.com); the first reachable one replaces the main host automatically. This is the "I'm in a region where HF is slow or blocked" button.
• Unzips safely - unzip_after_download extracts archives into the target folder with zip-slip validation.

The inputs that matter

• file_list - the URL + target lines. The whole job.
• skip_existing - skip files already present (default on).
• verify_size - integrity checking (default on).
• hf_token / modelscope_token / proxy_url - for gated repos and networks. ⚠️ The tooltips warn these are stored in the workflow JSON as plain text - don't share a workflow that contains a token.

No outputs - it's an action node that holds the run until the files land.

Installing it

Part of comfyui-timesaver (ComfyUI Manager → "Timesaver", or manual clone + pip install -r requirements.txt + restart). No models to download - it is the downloader.

Where people get burned

Three things. First, the token warning is real: a workflow with hf_token filled in and shared publicly hands your token out. Only use it in workflows you never export. Second, "Get models from workflow" is smart but not psychic - it depends on loaders carrying the URL metadata, and a loader from a pack that doesn't stamp it falls back to filename-only. When that happens, the downloader just won't know where to fetch from, and you add the line by hand. Third, remember it's sequential and blocking: the rest of the graph waits, which is the design (the models have to exist before anything loads them), but it means a slow mirror makes the whole run wait. If a download stalls, that's when the mirror list earns its keep - add a mirror domain and rerun.
