ACE, RAR, TAR, and ZIP files are all date containing files. They store one or several files in the compressed form. After you downloaded the compressed file, you need to unpack its contents in order to use it. Download one of the following programs to decompress the file:
These programs provide the complete support for compressed files, so you may both create and unpack them. If you installed a program on your computer and downloaded a compressed file, in most cases may double click on file icon to open it in the program.
Some compressed files can be parts of multi-volume sequences. In WinRAR you can split a huge archive to a few smaller files, which are called volumes. They may have extensions .rar (the first volume), .r00, .r01, ..., or .part1.rar (the first volume), .part2.rar, ..., etc. If you need to unpack volumes, place all them to the same folder and start extraction from the first volume.
