A .rar file is an archive file format that supports data compression, error recovery, and file spanning. It is commonly used to bundle multiple files together into a single compressed package, usually requiring software like WinRAR or 7-Zip to extract. Safety Advisory

A uniquely named file created locally (e.g., 47rB85T84C8484-05.rar ) that has not been indexed by public search engines.

Use updated security software to scan any unexpected .rar file before attempting to open or extract it.
