Smart File Renamer

Smart File Renamer 繁體中文說明 Automatically sanitize and rename uploaded files into clean, SEO-friendly names. It transliterates Latin diacritics, normalizes separators, strips non-ASCII characters, and lowercases both filenames and extensions to ensure compatibility across all operating systems. Key Features - Accents Transliteration: Uses WordPress built-in removeaccents() to map 200+ Latin accented characters (e.g. á - a, ü - u) to their ASCII equivalents. - Consistent Lowercase: Converts both filenames and file extensions to lowercase to prevent file path mismatches on case-sensitive hosting servers (e.g. Nginx on Linux). - Separator Normalization: Automatically converts spaces and underscores into hyphens (-). - Consecutive Hyphen Collapsing: Replaces multiple hyphens with a single hyphen and strips them from the beginning and end of the filename. - Safe Fallback: Generates a safe name (e.g., file-1718000000.png) if the entire filename consists of non-ASCII characters (like Chinese/Japanese/Korean) that get stripped. - Optional Date Prefix: Organize files chronologically with a toggleable YYYY-MM-DD prefix under Settings → File Renamer. - Optional Time-Based File Names: Store
