📁 Get File Path

Plenty of useful nodes take a path rather than an image tensor: the pack's own Groq transcription node wants an audio file path, "save text to file" nodes want somewhere to write, and a handful of video and audio loaders want a location on disk. 📁 Get File Path is the node that turns a file sitting in ComfyUI's input/ folder into strings you can feed those nodes.

One input, four outputs:

• full_file_path - the whole thing, absolute.
• file_path_only - the parent directory.
• file_name_only - the filename without the extension.
• file_extension_only - the extension, with its dot.

If the file doesn't exist, all four come back empty and you get a console message saying so, which is the usual cause of "why is my transcription node saying file not found".

The extension-with-dot, name-without-extension thing

Read that list again, because it's the one detail that catches people building filenames. file_name_only is the stem: my_song.mp3 gives you my_song, and file_extension_only gives you .mp3. So to rebuild the original name you concatenate them, and to write a sibling file you'd do file_path_only + "/" + file_name_only + ".txt". If you assumed file_name_only included the extension you'll produce my_song.mp3.txt, which works fine until something else tries to open it.

The tooltip on the output says "The name of the file" - the code says stem. Trust the code.

The input, and why it feels broken

image is a dropdown of files from your input directory. It is called image, but it accepts any file - the tooltip tells you to "select any file type when uploading a non-image file", i.e. use ComfyUI's own file picker prompt and switch the filter from the image types to any.

The author is upfront in the README that this should have a proper browse button and doesn't yet: "If you know how to add this, please let me know or do a pull request." So the workflow is: upload your .mp3 or .wav or .txt through this node's picker (which copies it into input/), then wire full_file_path downstream. It's clunky, it works, and it does mean your file ends up in input/ whether you wanted that or not.

Where it's genuinely useful

The strongest use in this pack is the pairing with ✨📝 Groq ALM API - Transcribe, whose file_path input is a plain string that must point at a real audio file. Drop Get File Path next to it, pick your track, wire full_file_path in, done - no copy-pasting Windows paths with escaped backslashes.

Its second life is namespacing: build output paths and filenames out of the pieces instead of retyping them, so a batch of files derived from reference_shot.png lands next to each other with predictable names.

Install

ComfyUI Manager → ComfyUI-mnemic-nodes, or:

cd ComfyUI/custom_nodes
git clone https://github.com/MNeMoNiCuZ/ComfyUI-mnemic-nodes

Restart. Nothing downloads for this node - it's pathlib and nothing else. The pack's other requirements (transformers, opencv-python, imageio, piexif, tiktoken, groq…) install alongside it because they're all in one requirements.txt, which is the standing annoyance with grab-bag packs: you want a path helper, you get a Python ML stack.
