Get File List

There's a whole class of ComfyUI workflows that are really just "do something to every file in this folder." Batch upscaling, batch img2img, processing a folder of reference images. The thing every one of those needs is a list of filenames, and Get File List is the node that produces it - it globs a directory into a STRING list with filtering and sorting built in.

It's the front door for batch processing in this pack. Hand it a path and a glob pattern and it walks the directory tree, filters to the file types you care about, sorts the results, and hands you a list you can feed into a batch loop, a picker, or a save/compare chain. Everything downstream that works on lists can now work on your actual files.

How it works

Under the hood it's Python's glob with recursive=True: it joins your path with glob_pattern and collects every match, recursively. Then it applies the extension filter, sorts according to your choice, and returns the list. The default pattern **/* grabs everything in the tree; the default extension list is your standard image set.

The inputs that matter:

• path (STRING, default ./) - where to look. Relative paths resolve against ComfyUI's working directory, so absolute paths are usually the safer bet.
• glob_pattern (STRING, default **/*) - **/* for all files recursively, or something like *.png to narrow the glob itself.
• sort_method - default, date (by file modification time), filename, parent folder, full path, or random (seeded by the seed input).
• sort_ascending (BOOLEAN, default on) - flip for newest-first or reverse alphabetical.
• allowed_extensions (STRING, default .jpeg,.jpg,.png,.tiff,.gif,.bmp,.webp) - comma-separated; leave blank to allow everything.
• dest_path (STRING, optional) - this one's clever: it excludes files whose base name already exists in dest_path, regardless of extension. Built for "skip images I already converted."

The output is file_list, a list of full paths ready for the next node.

Installing it

Get File List is one node in ComfyUI-TinyBee, the small MIT-licensed utility pack from TinyBeeman. No models, no heavy deps. Via Manager:

1. ComfyUI Manager → Custom Nodes Manager.
2. Search "ComfyUI-TinyBee" and install.
3. Restart ComfyUI.

Or clone:

cd ComfyUI/custom_nodes
git clone https://github.com/TinyBeeman/ComfyUI-TinyBee

Restart and it lives under 🐝TinyBee/Lists. Its jsonata dependency is only for the pack's JSON Parser node.

Gotchas

Path discipline is the thing that bites. ./ is relative to where ComfyUI launched, which is rarely where you think it is - when in doubt, use an absolute path. The date sort reads file mtime, so it reflects disk time, not the name. And dest_path matching is by base name with extension stripped, so photo.png in the source is skipped if any photo.* exists in dest. Pair the output with Filter List or Randomize List for the full batch-processing pipeline.
