Regex Editor & Tester

This regex matches simple URI-like strings starting with a single word character (letter, digit, or underscore), followed by ://, then zero or more path segments (containing letters, digits, hyphens, underscores, or spaces, each ending with /), and finally a filename with a dot and file extension. It is useful for extracting basic URLs or protocol references from text, though it does not support multi-letter schemes like http or https.
