I am having a frustrating time of late with .rar files downloaded from the web. The Unarchiver has served me well for the most part. But of late it has failed to open a number of .rar files correctly. As a result I have tried both MacPAR Deluxe and UnRarX. On occasion MacPAR has done the trick, but very infrequently. The files in question have all opened correctly on a Windows machine using 7-zip so the files themselves are not the problem. Any suggestions? I would much prefer to use my Mac for .rar purposes. Thanks in advance.
