A run of readable characters at least as long as the minimum you set, 4 by default. Letters, digits, punctuation, spaces and tabs count. A line break or any other byte ends the run.

ASCII, the plain text most programs store. UTF-16, two bytes per character, which Windows programs and resources use. UTF-8 picks up accented letters and other alphabets; it is off by default because random bytes often look like short UTF-8 text.

By its shape. A URL starts with a scheme like https://, an email has a name, @ and a domain, and an IP address is four numbers with dots. A path looks like /usr/lib/name or C:\Folder\name. A key or token is a long run of hex or base64 with enough mixed characters to look random. These are guesses: check each one yourself.

Files of a gigabyte or more work, with a progress bar and a Stop button. Every string is counted and drawn on the strip; the list keeps the first 200,000 so the page stays fast. Raise the minimum length to see fewer, longer strings.

One line per string in the list as it is filtered now: the offset in hex, a tab, then the string. A string longer than 4,096 bytes is cut there.
