A .rar file is a zipped file. To open it, one will need an unzipper programme such as WinRar. Though this claims to be free for only a trial period, this is untrue and will probably never be paid for.
To open RAR files on a Mac you will need an expander such as RAR Expander software (See links below). You can use free, open source Zipeg program from http://zipeg.com (or see link below) Zipeg opens RAR, ZIP and many other file formats and works on both Macintosh and Windows. It also supports filenames in national alphabets and provides quick pick inside the RAR and ZIP files if they contains pictures or photographs. Zipeg allows users to extract all or individually selected files and folders from archives.
you can use other programs also to open a rar file
You can extract rar files by downloading an extractor like WinRar or 7-zip. You can use WinMount to open a rar file without extraction, because WinMount can mount it to a new virtual disk.
can't open rar files at all. receive archive error message
RAR always split into several parts, using winmount to mount one of these parts, then all of parts will be mounted to a virtual disk. Open the virtual disk, you will see all files inside the rar.
Most decompression programs can handle .RAR's but WinRar works. Google it.
Adobe Reader is not for opening rar files. It is a compressed file which can contain one or more files. You need a piece of software like WinRar or Winzip to open it. There may be files in it that can then be opened by Adobe Reader.
To "unpack" a .rar file you need to install a decompression tool such as WinZip or WinRar. These will let you open .rar files and open the full files with applications that can read those (such as Microsift(TM) Word or OpenOffice for.doc files).
Use a program such as unRarX.
Extract the files from the RAR, then create the PUP file from the extracted files.

RAR files can only be read by certain programs that do not come with your computer. Some programs for Windows computers are WinZip, RarZilla, IZarc, PeaZip, Zipeg, and ALZip. Programs for Mac users are Stuffit Expander, The Unarchiver, amd Zipeg.
