Every ComfyUI workflow eventually needs a file path, and typing long absolute paths into a text box is the worst part of the job. Path Collector is the pack's answer: a multi-line box where you paste a list of paths, plus a file-picker button that opens a real dialog so you can select files or a folder without touching the keyboard. Whatever you gather comes out as a single newline-separated string on paths_out.

It's boring in the best way, and it sits at the head of a small path-handling family in this pack - feed its output into IndexSelectorNode to pick one line, or PathValidatorNode to check the paths exist. In the WanAnimate multi-ref workflow it's how the "secondary reference images" directory gets loaded: one node, a folder pick, done.

What you set

• paths - multi-line input, one path per line. Paste, or use the multi-file picker frontend control.
• index - the surprise feature. 0 (default) outputs all lines. 1 outputs line 1, 2 outputs line 2, etc., 1-based. Out of range outputs an empty string. So the same node doubles as "collect everything" and "grab one."

The picker dialog is worth knowing about: it's implemented as a backend route that pops a native tkinter file dialog, which is why the pack's install.py includes a tkinter repair step for embedded Python installs. If you're running ComfyUI from the standalone Windows package and the picker button does nothing, that repair step (re-run install.py, restart) is the fix.

When you'd reach for it

• Gathering a batch of reference images or pose files without hand-typing a directory listing.
• Feeding a multi-line path list downstream to an index selector or a validator.
• Any workflow where the same set of files gets reused - it makes the paths a single editable source of truth (the KB's node-plumbing doc calls this the whole point of the plumbing layer: one source, many consumers).

Install

Part of user2318/ComfyUI-CustomNodeKit. ComfyUI Manager: search "CustomNodeKit". Or:

cd ComfyUI/custom_nodes
git clone https://github.com/user2318/ComfyUI-CustomNodeKit.git
cd ComfyUI-CustomNodeKit
pip install -r requirements.txt

then restart. No models.

The gotcha

Two things. First, the picker needs tkinter, and on headless/minimal Python installs it's often missing - the pack ships an auto-fix but a manual install that skips install.py won't get it; if the dialog fails, run the install script. Second, index here is 1-based while IndexSelectorNode is 0-based - a genuinely annoying inconsistency in the same pack (index 1 in this node = line 1, index 1 in Index Selector = line 2). If you chain them, don't pass the same number through and expect the same line. The output is also just a string: nothing validates that the paths are real until a downstream node actually tries to open them, which is exactly why the validator node exists.
