Save Image + Prompt TXT (Copy & Reveal)

ComfyUI SaveImagePlusPrompt

A standalone image-saving node for ComfyUI, inspired by LayerUtility: SaveImagePlus V2 from ComfyUI_LayerStyle_Advance (MIT license, thanks to chflame163).

Node name: Save Image + Prompt TXT (Copy & Reveal) (category: image, internal class name in workflow JSON: SaveImagePlusPrompt)

What it does

• Saves images (jpg/png) with sequential numbering, custom output folder on any drive, optional timestamp, quality/DPI settings, and optional workflow metadata (PNG) or workflow JSON sidecar.
• Saves the prompt as a .txt file with the exact same filename as the image, in the same folder. Example: image_00007.jpg + image_00007.txt. The prompt is whatever string you connect to the prompt_text input.
• Reveal in file manager button: one click opens the system file manager with the last saved image selected (Windows Explorer, macOS Finder, Linux file manager).
• Save Training File button: one click copies the last saved image together with its matching .txt (and .json, if present) to any folder you enter in the copy_to_folder field - keeping identical filenames. This is a pure file copy (byte-identical), nothing is re-generated. Useful for sorting keepers into a separate folder right after generation.
• Delete Last Generated Image button: removes the last saved image and its .txt/.json sidecars (only those files) after a confirmation dialog - for discarding bad generations on the spot.

Installation

1. Clone or copy this folder into ComfyUI/custom_nodes/:

git clone https://github.com/Slartibart23/ComfyUI_SaveImagePlusPrompt_v1.4.0_save-node_prompt-txt_reveal-copy-delete-buttons.git

2. Restart ComfyUI. No additional packages are required.
3. After updating: press Ctrl+F5 in the browser once so the frontend extension (buttons) reloads.

Inputs

• images: image input, as with any save node.
• prompt_text (optional): the prompt string to save as .txt - e.g. from a text node, or from the text widget of a CLIP Text Encode node (right-click the node → Convert widget to input → text, then wire it to both the encoder and this node). If empty or unconnected, no txt is written.
• custom_path: custom output folder. Empty = ComfyUI's default output folder.
• filename_prefix: filename prefix, may contain subfolders (project/img). %date and %time are replaced with the current date/time.
• timestamp: optional timestamp in the filename (None / second / millisecond).
• format: jpg or png.
• quality: image quality 10-100.
• dpi: DPI value written into the file.
• meta_data: embed workflow metadata into PNG (PNG only).
• save_workflow_as_json: additionally save the workflow as a .json sidecar.
• preview: show a preview in the ComfyUI window.

The node scans the target folder for existing images and continues the sequential numbering (_00001, _00002, ...). The txt file always uses the same name as the image just saved.

Buttons on the node

Reveal in file manager - after each run, the node remembers the path of the last saved image (for batches: the last image of the batch). The button opens the file manager with that file selected. The remembered path only lives for the current ComfyUI session; before the first run the button shows a friendly message instead.

Save Training File - enter a target folder in the copy_to_folder text field (the value is stored in the workflow), then click the button to copy the last saved image + its .txt/.json sidecars into that folder with identical filenames. Existing files with the same name are replaced.

Delete Last Generated Image - deletes the last saved image together with its .txt/.json sidecars from the original output folder (only these files, nothing else). A confirmation dialog protects against accidental clicks. Useful for discarding bad generations immediately.

Security note: the server endpoints only reveal, copy, or delete paths this node itself saved during the current session - the frontend cannot operate on arbitrary paths.

Compatibility & requirements

• Works with current ComfyUI versions on Windows, macOS, and Linux (the "Reveal" button opens Windows Explorer, macOS Finder, or the default Linux file manager).
• No additional Python packages required - only the standard ComfyUI environment (Pillow, numpy).
• The buttons are provided by a small frontend extension (web/ folder); after updates, reload the browser with Ctrl+F5.
• Existing workflows keep loading unchanged: the buttons are not serialized into widgets_values, and the copy target folder is stored in the node's properties.

Version history

• v1.4.1 - "Reveal in file manager" on Windows now starts Explorer without a shell (safer with unusual file names); fixed the git clone URL in the README.
• v1.4.0 - "Copy to folder" renamed to "Save Training File"; new "Delete Last Generated Image" button (removes image + txt/json sidecars, with confirmation).
• v1.3.0 - node display name and all UI messages in English; README rewritten.
• v1.2.x - "Copy to folder" button + target folder field; guard against duplicate route registration on startup.
• v1.1.0 - "Reveal in file manager" button.
• v1.0.0 - initial release: image saving with matching prompt txt.
