QuestionWhen I open hidden text from an image sent to me in Notepad, it looks like a bunch of characters, letters, symbols, etc. How do I sort it out to read?ArroganceTop AnswererAs the article says, you're expected to scroll down to the bottom of the file, either with the scrollbar or the Page Down button. Because you're simply concatenating unpredictable plain text, and not a file type with specific headers, like zip or rar, there's no simple way to filter it. If you standardized the beginning of a line with something predictable like "MESSAGE: Hello! ", you could filter it in the Command Prompt with 𝐟𝐢𝐧𝐝𝐬𝐭𝐫 "𝐌𝐄𝐒𝐒𝐀𝐆𝐄:" 𝐢𝐦𝐚𝐠𝐞.𝐣𝐩𝐠
