the [number]- prefix is automatically added when Add number to filename when saving is enabled (default), it itself is not a Pattern.

A different image filename and optional subdirectory and zip filename can be used if a user wishes.

Image filename pattern can be configured under.

Subdirectory can be configured under settings.

Zip archive can be configured under settings.

Patterns

Web-Ui provides several patterns that can be used as placeholders for inserting information into the filename or subdirectory, user can chain these patterns together, forming a filename that suits their use case.

`[datetime<Format><TimeZone>]`	Datetime at specific <Time Zone> in specified <Format>	[datetime<%Y%m%d_%H%M%S_%f><Asia/Tokyo>]` 20221025_014350_733877
`[job_timestamp]`	job start time in "%Y%m%d%H%M%S"	20221025013106
`[prompt_no_styles]`	Prompt without Styles	1girl, white space, ((very important)), [not important], (some value_1.5), (whatever), the end
`[prompt_spaces]`	Prompt with Styles	1girl, white space, ((very important)), [not important], (some value_1.5), (whatever), the end , (((crystals texture Hair)))，(((
`[prompt]`	Prompt with Styles, `Space bar` replaced with`_`	1girl,___white_space,_((very_important)),_[not_important],_(some_value_1.5),_(whatever),_the_end,_(((crystals_texture_Hair)))，(((
`[prompt_words]`	Prompt with Styles, Bracket and Comma removed	1gir white space very important not important some value 1 5 whatever the end crystals texture Hair ， extremely detailed
`[prompt_hash]` `[prompt_hash<N>]`	The first 8 or `N` characters of the prompt's SHA-256 hash	1girl -> 6362d0d2 (1girl:1.1) -> 0102e068
`[negative_prompt_hash]` `[negative_prompt_hash<N>]`	The first 8 or `N` characters of the negative prompt's SHA-256 hash	1girl -> 6362d0d2 (1girl:1.1) -> 0102e068
`[full_prompt_hash]` `[full_prompt_hash<N>]`	The first 8 or `N` characters of the `<prompt> <negative_prompt>`'s SHA-256 hash	1girl -> 6362d0d2 (1girl:1.1) -> 0102e068
`[clip_skip]`	CLIP stop at last layers	1
`denoising`	denoising_strength if applicable	0.5
`[batch_number]`	the Nth image in a single batch job	BatchNo_[batch_number] -> BatchNo_3
`[batch_size]`	Batch size	[1234567890,1234567891,1234567892,1234567893] -> 4
`[generation_number]`	the Nth image in an entire job	GenNo_[generation_number] -> GenNo_9
`[hasprompt<prompt1\|default><prompt2>...]`	if specified `prompt` is found in prompts then `prompt` will be added to filename, else `default` will be added to filename (`default` can be blank)	[hasprompt] -> girl [hasprompt<girl\|no girl><boy\|no boy>] -> girlno boy
`[user]`	the username used to login to webui when using `--gradio-auth username:pass`	username
`[image_hash]` `[image_hash<N>]`	The first `N` characters or the full SHA-256 hash of the image (the image itself not the file)	484a1e7a07e7573a9081ab6a527990bb4d410dc3
`[none]`	Overrides the default, so you can get just the sequence number

If <Format> is blank or invalid, it will use the default time format "%Y%m%d%H%M%S" tip: you can use extra characters inside <Format> for punctuation, such as _ -

If <TimeZone> is blank or invalid, it will use the default system time zone

If batch size is 1 the [batch_number], [seed_last] along with the previous segment of text will not be added to filename

If batch size x batch count is 1 the [generation_number] along with the previous segment of text will not be added to filename

[batch_number] and [generation_number] along with the previous segment of text will not be added to filename of zip achive.

The Prompts and Style used for the above [prompt] examples Prompt:

1girl,   white space, ((very important)), [not important], (some value:1.5), (whatever), the end

Selected Styles:

(((crystals texture Hair)))，(((((extremely detailed CG))))),((8k_wallpaper))

note: the Styles mentioned above is referring to the two drop down menu below the generate button

if the prompt is too long, it will be cutoff

this is due to your computer having a maximum file length

Add / Remove number to filename when saving

you can remove the prefix number by unchecking the checkbox under

Settings > Saving images/grids > Add number to filename when saving

with prefix number

without prefix number

Caution

The purpose of the prefix number is to ensure that the saved image file name is Unique. If you decide to not use the prefix number, make sure that your pattern will generate a unique file name, otherwise files may be overwritten.

Generally, datetime down to seconds should be able to guarantee that file name is unique.

[datetime<%Y%m%d_%H%M%S>]-[seed]

20221025_014350-281391998.png

But some Custom Scripts might generate multiples images using the same seed in a single batch,

in this case it is safer to also use %f for Microsecond as a decimal number, zero-padded to 6 digits.

[datetime<%Y%m%d_%H%M%S_%f>]-[seed]

Filename Pattern Examples

If you're running Web-Ui on multiple machines, say on Google Colab and your own Computer, you might want to use a filename with a time as the Prefix. this is so that when you download the files, you can put them in the same folder.

Also since you don't know what time zone Google Colab is using, you would want to specify the time zone.

[datetime<%Y%m%d_%H%M%S_%f><Asia/Tokyo>]-[seed]-[prompt_words]

20221025_032649_058536-3822510847-1girl.png

It might also be useful to set Subdirectory the date, so that one folder doesn't have too many images

[datetime<%Y-%m-%d><Asia/Tokyo>]
