What is a "zipped" file?

A "zipped" file (i.e., with a file extension of ".zip") has become, for better or for worse, the de facto standard for file archives, supplanting earlier archiving schemes such as ".arc" , ".lha" and even the iconic ".lzh".

A "zipped" file is a special file that contains one or more files, in compressed form. In other words, a zipped file is a compressed archive file used to make large files and collections of files more manageable to the end user, especially when downloading and emailing.
