Which symbols may not be used when naming a file?

When naming a file, certain symbols are generally prohibited to prevent issues with file systems. Commonly disallowed characters include: slashes (/) and backslashes (), colons (:), asterisks (*), question marks (?), quotes ("), angle brackets (<, >), and pipe symbols (|). These characters can interfere with file path interpretation or have special meanings in operating systems. It's best to stick to alphanumeric characters, dashes (-), and underscores (_) for file names.
