SaveImageTextDataSetToFolder - ComfyUI Built-in Node Documentation

Save Image-Text (to Folder) saves a dataset of image and text caption pairs to a folder inside ComfyUI’s output directory.

Save Image-Text (to Folder) saves a dataset of image and text caption pairs to a folder inside ComfyUI’s output directory. Each image is written as a PNG file, and its matching caption is written as a TXT file with the same base filename, so every image ends up paired with its description.

Inputs

Parameter	Description	Data Type	Required	Range
images	List of images to save.	IMAGE	Yes	-
texts	List of text captions to save. This input is optional.	STRING	No	-
folder_name	Name of the folder to save images to (inside output directory). (default: “dataset”)	STRING	Yes	-
filename_prefix	Prefix for saved image filenames. (default: “image”)	STRING	Yes	-
mode	Whether to overwrite existing files or increment filenames to avoid overwriting. (default: “overwrite”)	COMBO	Yes	”overwrite" "increment”

Note: The images input is a list, and the node receives both images and texts as lists. The texts input is optional; if provided, it should be a list of text captions and should contain the same number of items as images. Each caption is saved as a .txt file corresponding to its paired image. In overwrite mode, files are named {filename_prefix}_{index}.png and replace any existing files with the same name. In increment mode, a unique counter is added to the filenames so existing files are not overwritten. The folder_name must resolve to a path inside the output directory; folder names that try to escape it (for example with ..) are rejected.

Outputs

Output Name	Description	Data Type
-	This node returns no data. It saves files directly to the filesystem.	-
