Directory Listing

ComfyUI has no native "loop over the files in this folder". You end up hand-naming inputs, pasting paths, or hardcoding a batch size and hoping. This node is the honest fix: it lists what's in a folder and hands it to the graph as lists on wires - full paths on one, bare names on another, the count beside them - so a For Loop takes one file per iteration and processes a whole folder without you typing a single filename.

Its natural partner is the WAS For Loop Open/Close pair - the node's own tooltips spell out the pattern: wire paths and count into a For Loop to open one file per iteration, and carry the matching names along so each saved render keeps the filename it was made from.

The inputs that matter

• folder - which folder to read, from a dropdown. A bare input, output or temp names ComfyUI's own folders; plates/shot_01 [input] is a folder below one of them. Any folder you've added under paths.allow_read in config.yaml appears under its own name.
• pattern - a glob. * is everything, *.png only PNGs, frame_*.png one numbered run. Matching happens inside the folder - a drive, a leading slash or a .. segment is refused, which is the pack not letting you walk the whole filesystem by accident.
• recursive - false lists only what sits directly in the folder; true applies the pattern at every depth.
• include - files, directories, or both. A loop over images wants files; directories walks a set of shot folders.
• sort - order matters more than it looks. natural reads digit runs as numbers, so frame_2 comes before frame_10. Plain name sorts alphabetically and puts frame_10 first. modified gives oldest first, size smallest first.
• reverse and limit - flip the order, and keep only the first N once sorted. With modified + reverse + limit 10 you get the ten newest files, which is the classic "latest render at index 0" setup.

What comes out

• paths (ARRAY) - every entry's full path, in order, for Text List Get / Slice / Length or a loop.
• names (ARRAY) - the same entries named below the folder, in the same order, so entry 3 here belongs to path 3. Wire names into an Image Save's filename prefix and results keep their original names through the whole round trip.
• listing (STRING) - names one per line, for a preview or for re-cutting with Text Split to List.
• count (INT) - the length of both lists. Feed it to a For Loop's iterations and you walk the entire directory.

Installing it and the gotchas

Standard WAS Node Suite v3 install: ComfyUI Manager → search WAS Node Suite v3, or clone into custom_nodes. No weights, no extra dependencies.

Three failure modes worth knowing before you hit them. A folder that isn't there stops the prompt - loudly, on purpose, because silently listing nothing would be worse. A folder that's there but holds nothing the pattern matches answers empty lists and a count of 0, which is the silent case to guard against in a loop. And names starting with a dot are only matched by a pattern that starts with one, so *.png won't touch your hidden .png cache files - usually a feature.
