Downloading and unzipping files

Lately there have been some visitors who do not know about the fact that these music blogs usually put whole albums into a compressed file, usually a ZIP or an RAR (there are others but these are the most popular) for uploading and downloading. For those of you who have little use for compression/decompression software, you can download a freebie called 7-ZIP from the web and once installed, it will readily decompress the files into their individual folders (albums) and mp3 tracks.  A double left click on the downloaded file will result in the unzipping software opening the files so the other files within it can be extracted. select "extract" or similar and, if you wish, nominate where you want the file to be extracted to
