A new folder will appear containing the actual files (such as game ROMs, documents, or media). 4. Safety Warning
A .RAR file is a "compressed" folder. People use this format to bundle multiple files into one smaller file for easier sharing or storage.
Compressed files are a common way to spread malware because antivirus software sometimes struggles to scan inside the archive until it is opened.
Unlike a standard folder, you cannot simply double-click it to see what's inside unless you have specialized software installed. 2. How to Open the File
Use a tool like VirusTotal to upload the .rar file and check it against dozens of antivirus engines before you extract it.
