Instead of a flat list of files, you can group them by purpose. ## Default categories When your firm is set up in Arkata, a default set of categories is created. These can be customised to match how your firm organises files. ## Assigning a category When uploading a document (or editing an existing one), you can assign it to a category from the dropdown. This is optional — documents without a category still appear in the full list. ## Managing categories Your firm can create, rename, and delete custom categories: 1. Go to **Settings** or the project's document settings 2. Manage the available categories 3. New categories become available immediately for all projects Deleting a category doesn't delete documents in it — they simply become uncategorised. ## Tips for using categories well * Keep the list short and meaningful (e.g. "Drawings", "Submissions", "Correspondence", "Photos") * Use consistent naming across projects so team members always know where to file things * Don't over-categorise — 5-8 categories is usually enough
