Opening a standard text file (.txt) is generally completely safe because these files consist exclusively of raw, unformatted text characters and lack any capability to run code, trigger macros, or execute hidden software instructions on your computer. When you double-click a text file, your operating system opens it inside a lightweight text viewer or editor that simply displays the readable characters on the screen. The only theoretical risk arises if a malicious actor attempts a sophisticated spoofing technique by hiding an executable file extension behind a fake text label. As long as your operating system displays real extensions and you verify the source, opening a text file carries no security hazards.
