Add or remove instance files

Fable's instance Files section can list files and folders but does not provide in-app controls to add, replace, rename, or delete arbitrary files. Use the launcher’s supported Content, Worlds, and Import/Export workflows when they apply. For other files, use your operating system's file manager.

Add a file

1. Stop Minecraft for the selected instance and wait for active downloads or installation jobs to finish.
2. Open Library → instance → Instance Settings and note the configured game directory.
3. Make a backup of the destination directory before changing it.
4. Copy only files from a source you trust into the intended instance directory. For example, a mod JAR belongs in mods, a resource pack in resourcepacks, and a shader pack in shaderpacks. Use the instance Content screen's Upload files action for local mod JARs when available; this tracks those files in Fable.
5. Return to the instance's Files view and verify the destination before launching.

Remove a file

Use the relevant tracked-content Remove action, the Worlds delete action, or the import/archive workflow where applicable. These controls understand the item Fable manages. For a manually added file that is not tracked, stop Minecraft, confirm the selected instance and exact path in your file manager, and move the file to a temporary backup location before permanently deleting it.

Do not remove Minecraft libraries, loader files, instance metadata, or files while the game is running. If you are unsure what owns a file, leave it in place and ask support. See Edit configuration files, Game directory and instance files, and Import and export.
