I had to download a third party sw to unpack some .rar files of style files that were sent to me. Once I dl and installed the sw I was able to unpack the style files. Sometime later I noticed that I had a zip file with the .rar suffix on it. I started looking into my zip files and discovered that all of them are now .rar files. I guess that software converted them all. I like zip better but have no idea how to convert them all back to zip files.
