Customize the information saved in file- and folder names. Use the values of sampler parameters as part of file or folder names.
Save data about the generated job (sampler, prompts, models) as entries in a json (text) file, in each folder.

Parameters / Usage

Attribute	Description
`filename_prefix`	String prefix added to files.
`filename_keys`	Comma separated string with sampler parameters to add to filename. E.g: `sampler_name, scheduler, cfg, denoise` Added to filename in written order. `resolution` also works. `vae_name` `model_name` (upscale model), `ckpt_name` (checkpoint) are others that should work. Here you can try any parameter name of any node. As long as the parameter has the same variable name defined in the `prompt` object they should work. The same applies to `foldername_keys`.
`foldername_prefix`	String prefix added to folders.
`foldername_keys`	Comma separated string with sampler parameters to add to foldername. Add more subfolders by prepending "./" to the key name.
`delimiter`	now a free field Delimiter character or word, can be anything your file system supports. Windows users should still use "/" for subfolders.
`save_job_data`	If enabled, saves information about each job as entries in a `jobs.json` text file, inside the generated folder. Mulitple options for saving `prompt`, `basic data`, `sampler settings`, `loaded models`.
`job_data_per_image`	When enabled, saves individual job data files for each image.
`job_custom_text`	Custom string to save along with the job data. Right click the node and convert to input to connect with another node.
`save_metadata`	Saves metadata into the image.
`counter_digits`	Number of digits used for the image counter. `3` = image_001.png. Will adjust the counter if files are deleted. Looks for the highest number in the folder, does not fill gaps.
`counter_position`	Image counter first or last in the filename.
`one_counter_per_folder`	Toggles the counter. Either one counter per folder, or resets when a parameter/prompt changes.
`image_preview`	Turns the image preview on and off.
`output_ext`	File extension: PNG by default, or WEBP (coming soon).

Unknown key names in filename_keys and foldername_keys are treated as custom strings.

Node inputs

images - The generated images.

Optional:

positive_text_opt - Optional string input for when using custom nodes for positive prompt text.
negative_text_opt - Optional string input for when using custom nodes for negative prompt text.

Automatic folder names and date/time in names

Convert the 'prefix' parameters to inputs (right click in the node and select e.g 'convert foldername_prefix to input'. Then attach the 'Get Date Time String' custom node from JPS to these inputs. This way a new folder name can be automatically generated each time generate is pressed.

Disclaimer: Does not check for illegal characters entered in file or folder names. May not be compatible with every other custom node, depending on changes in the prompt object. Tested and working with default samplers, Efficiency nodes and UltimateSDUpscale.

Happy saving!

RoadMap

I won't promise anything, just like @thedyze did not promise anything when they released this custom node. Then disappeared for good 3 months later. That's fine, I do that too.

However, I do provide a way to contact me, and will accept PR and collabs. Once I feel like I don't have time to work on it, I will gladly transfer ownership or let collabs maintain it.

now accepts inexistant keys and use them as fixed strings
now accepts inexistant keys with / and use them as subfolders
delimiter is now whatever you want, free field. Limited to 16 characters tho
all is instance methods, previously we had @staticmethods. Why? Don't know.
check get_latest_counter: does it still work with subfolders? yessir
bugfix: custom_name was not updated for int and floats
add what I was looking for the last 6 months in the first place: %node.attribute% from any node.
add what I was looking for the last 6 months in the first place: #000.attribute from any node.
bugfix: when using /name in foldername_keys, Comfy thinks you want to save outside the output folder
what is job_custom_text?
what is jobs.json? History, alraight. What do you do with that? Can we disable it?
improve get_latest_counter: fails when user renames files: appends text after counter
integrate pngquant
integrate optipng
integrate avif? can it hold metadata?
integrate webp
