For Windows users we offer zip-compressed archives that are compatible with WinZip by WinZip International LLC. or the DOS-based PKZIP by PKWARE, Inc. For UNIX/Linux users we recommend tar-archives compressed with gzip or bzip2. All methods provide lossless compression and cause corrupted archives to trigger error messages while extracting the content. After extraction applications can be used in the usual way.
