SaveImageTextDataSetToFolder - ComfyUI Built-in Node Documentation

Save Image-Text (to Folder) saves a list of images and their matching text captions to a specified folder inside ComfyUI’s output directory. For each image saved as a PNG file, a matching TXT file with the same base name is created to store its caption, which makes it useful for creating organized datasets of generated images paired with their descriptions.

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. 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.
