How to open a .rar file
You can open it with: WinRAR, 7-Zip. If it does not open, check that the file is not damaged and that you have downloaded it fully; also confirm that the extension was not renamed by mistake.
Quick tips
Never rename a file just to change its extension, because that does not convert the data inside. Use a proper converter or the Save As / Export option. Keep a backup copy of important archive files before editing them.
