'' These are common UNIX files which contain uncompressed data. '' '' So what is this useful for? Well, it allows you to effectively combine multiple '' files into a single file for downloading. The TAR files are readable and extractable '' by a wide variety of tools, including the very widely distributed WinZip. '' '' This script can include two types of data in each archive, file data read from a disk, '' and also things direct from memory, like from a string. The archives support files in '' a binary structure, so you can store executable files if you need to, or just store '' text. '' '' This class was developed to assist me with a few projects and has grown with every '' implementation. Currently I use this class to tarball XML data for archival purposes '' which allows me to grab 100''s of dynamically created XML files in a single download.
