        "content": "In Emacs, setting\n\n```lisp\n(setq make-backup-files nil)\n(setq auto-save-default nil)\n```\n\nturns off backup files (e.g. `file~`) and most auto-save files (e.g. `#file#`) *during editing*. But Emacs *still* creates or uses a directory `auto-save-list` in `~/.emacs.d/auto-save-list/` to store metadata about auto-saves\u2014specifically, information that helps it recover files after a crash. So, even if you've disabled auto-saving, Emacs may create this directory unless you explicitly tell it not to.\n\n---\n\n## Why `auto-save-list` still shows up\n\n- The variable `auto-save-list-file-name` determines where Emacs stores the auto-save-list file (files that track what buffer needs recovery). If `auto-save-list-file-prefix` is non-`nil`, Emacs will initialize `auto-save-list-file-name` based on that prefix and create the directory. ([emacs.stackexchange.com](https://emacs.stackexchange.com/questions/18677/prevent-auto-save-list-directory-to-be-created?utm_source=openai))  \n- Thus, disabling auto-saving and backups doesn\u2019t stop **auto-save list** files from being used/created. The auto-save list is orthogonal to the actual auto-save contents. ([gnu.org](https://www.gnu.org/s/emacs/manual/html_node/emacs/Auto-Save-Files.html?utm_source=openai))\n\n---\n\n## How to prevent `auto-save-list` directory creation\n\nTo disable creation of the auto-save-list directory, you'll need to set the relevant prefix variable to `nil`. Add the following line **before** you enable or set anything that relies on auto-saving:\n\n```lisp\n(setq auto-save-list-file-prefix nil)\n```\n\nThis stops Emacs from initializing `auto-save-list-file-name`\u2014so it won't try to save anything there. ([emacs.stackexchange.com](https://emacs.stackexchange.com/questions/18677/prevent-auto-save-list-directory-to-be-created?utm_source=openai))\n\n---\n\n## Example updated config\n\nHere\u2019s a sample minimal config snippet that should disable backups, auto-saving, **and** the auto-save-list directory:\n\n```lisp\n(setq make-backup-files nil)       ;; no backup~ files\n(setq auto-save-default nil)       ;; disable auto-save #file#\n(setq auto-save-list-file-prefix nil) ;; disable auto-save-list files / dir\n(setq create-lockfiles nil)        ;; disable .#lock files too (see below)\n```\n\n---\n\n## What about `.#` files (lockfiles)?\n\nYou mentioned files starting with `.#`\u2014those are *lockfiles*, not auto-save or backup files. These are created to prevent simultaneous editing of the same file in multiple Emacs instances. Even if you disable auto-save and backups, lockfiles may still appear unless you disable them:\n\n```lisp\n(setq create-lockfiles nil)\n```\n\nThis setting prevents Emacs from creating those `.#[filename]` files. ([reddit.com](https://www.reddit.com/r/emacs/comments/ytq5w8?utm_source=openai))\n\n---\n\n## Summary\n\n| Your current settings | What directories/files allowed | To add/manage |\n|------------------------|-------------------------------|----------------|\n| `(setq make-backup-files nil)` | No backup `~` files | You\u2019re good here. |\n| `(setq auto-save-default nil)` | Disables auto-save `#file#` files | Good. |\n| \u2014 | `auto-save-list/` directory still created | Add `(setq auto-save-list-file-prefix nil)` |\n| \u2014 | `.#[file]` lockfiles may still appear | Add `(setq create-lockfiles nil)` |\n\n---\n\nIf after adding those settings you **still** see the `auto-save-list` directory, make sure they are loaded *very early*\u2014before any packages or built-in modes that enable auto-saving or cause Emacs to read/write the recovery metadata. For instance, put them near the top of your `init.el` (or `.emacs`). Also, restart Emacs completely (don\u2019t just reload)."
