Glob Files (Yogurt Nodes)

There's a moment in every batch workflow where you realize you're about to wire the same image path into twelve nodes by hand. Glob Files is the "no thanks" button for that. Point it at a folder, give it a pattern, and it returns a LIST of matching file paths - which you can then index, slice, or feed into whatever loader the rest of your graph uses.

It's one of the I/O nodes in the YogurtNodes pack (yogurt7771/ComfyUI-YogurtNodes), and it's the piece that turns "I have 300 renders" into "I have a list I can loop over." Think of it as a poor man's batch scheduler: grab every *.png, sort them, walk them one at a time.

How it works

Under the hood it's Python's pathlib glob - the same pattern syntax you already know from the terminal. *.txt matches files in the root, **/*.py recurses into subfolders. You get a glob_mode toggle: glob walks left-to-right from the root, rglob walks right-to-left (useful when your pattern anchors on the filename and you want it matched against every directory level). The output is a single file_paths LIST.

The genuinely useful part is the filtering, which saves you from writing clever patterns at all:

• files_only - drop directories, keep files.
• extension_list - "txt,py,json" keeps only those, case-insensitive. Set extension_is_image and it treats the list as image extensions.
• prefix_list / suffix_list - comma-separated name filters like pre-1,pre-2.
• sort_files + sort_reverse - alphabetical order, ascending or descending. Leave sorting off and you get whatever order the filesystem gives you, which will not be the order you want.

Inputs that matter

• root_directory - where to start. If you leave it empty you'll glob relative to ComfyUI's working directory, which is almost never what you meant.
• glob_pattern - multiline, one pattern per line; empty lines are ignored. The default * is fine for a flat folder.
• extension_list - the filter you'll reach for most. "png,jpg,jpeg" and done.

The path-flavored toggles (as_posix, full_path, resolve_path, relative) mostly matter when you're on Windows or handing paths to other tools. as_posix swaps backslashes for /; resolve_path makes paths absolute and chases symlinks; relative returns paths relative to root_directory instead of absolute.

Output: file_paths - a LIST. Wire it to a ListIndex or a loop, or pair it with ListConcat / ListBinaryOps to merge a few globs into one batch.

Install

YogurtNodes is one clone away - via ComfyUI Manager (search "YogurtNodes") or:

cd ComfyUI/custom_nodes
git clone https://github.com/yogurt7771/ComfyUI-YogurtNodes.git
cd ComfyUI-YogurtNodes
pip install -r requirements.txt

Then restart ComfyUI; the node lives under Yogurt Nodes / IO. No models, no API keys, nothing heavy - this one's pure Python.

Troubleshooting

The common complaints, in order of how often I see them:

• "It returned nothing." Check root_directory actually exists and the pattern matches - a * with files_only on a folder of only-directories gives you an empty list, by design. And remember glob_pattern is multiline: a stray empty line is ignored, but a pattern with a typo just matches nothing.
• Recursion. If you want files in subfolders you need ** in the pattern (**/*.png) or rglob mode. Plain *.png only looks in the root.
• Windows path confusion. Backslash-heavy absolute paths are a classic gotcha when you hand the output to other nodes. Flip as_posix on if a downstream tool chokes.
• Batch order isn't "natural". With sort_files off, filenames can come back in filesystem order, which for numbered files means 1.png, 10.png, 2.png. If order matters, turn on sort_files - or sort numerically downstream with a list sort node.
