=====File Type Guidelines=====
Archives are usually single files which contain a set of other files. Usually archive formats are compressed, but they also offer other features such as encryption and data integrity, or the ability to split themselves into equal size chunks (eg. to store on floppy disks) but still operate as a single file. When you open an archive and grab a file out of it, that is usually referred to as 'extraction' - eg. 'extract the files from the Zip archive.'
The most common archive format on the Windows platform. Since Windows XP you don't need any special software to open them, it's built in to Windows Explorer, but most add-on file archive utilities will also handle Zip files.
A Unix format with no compression, directory structures and permissions are preserved, however. On Unix or Linux it is usual to use a separate utility to build the archive than the one you use to compress it.
The Gnu Zip utility - compatible with Windows Zip format. A .tgz file is a Tar archive which has been compressed with Gzip.
