What program do I use to unrar this type of files ?

I dl seven files but I can’t unzip I have winrar but it don’t matter it won’t work. Winrar tells me that the archive is damaged or unrecognizable. Which I know it’s not damaged. cause I dl other movies this week that had this type of file naming and samething not working.
Most of the time files end with .zip or .rar but not these. All files named the same except for a diff # at the end of file name. For example OfMisty_oven.avi.001 is the name of one of the seven files that once unzipped make a single file. For about a year now I’ve had this problem and usually I just delete them and get it somewhere else but I’m sick of this and want to know how to unzip it. Don’t seem like anybody else is having prob with these types of files. thanks
