Other archive formats, including RAR and 7-Zip, also allow passwords. These formats have a special ability to also encrypt the names of the files contained in the archive file using the supplied password , in addition to file content. Details for each file type are provided below. The ZIP File Format The ZIP file format is notable for being both an archive file format which can contain multiple files and folders as well as a compression file format which means the file data itself can be compressed.
Although ZIP files are by far the most common such compressed archive format, there are others, described below. The ZIP file format is notable for supporting many different compression methods. The traditional compression method used by ZIP files, referred to as Deflate , is by far the most common. Full support is provided for ZIP files using any of the above compression methods, including encrypted ZIP files requiring a password to open. The RAR format dates back to the early s, and can provide high compression ratios producing smaller files.
RAR is a highly proprietary format, and RAR files may only be created using the WinRar software program or companion command-line tool. Fortunately, the ability to open and decompress RAR files is "open source" and there are many programs that can do this, including ZIP Extractor. This includes full support for RAR files with a password. In practice, however, 7-Zip files created with these compression methods are rare. Notably, the 7-Zip format provides support for filters , which can lead to greater compression ratios on certain types of files.
ZIP extractor supports opening all variants of 7-Zip files, using any combination of compression method and filter. This also includes full support encrypted and password-protected 7-Zip files. Being an archive format , TAR files do not involve compression at all. Instead, the purpose of a TAR file is to group together or archive sets of files and folders in a reliable way.
TAR is a well established, long-running file archiver program that has received important updates over the years. It is generally considered well suited to the task of "archiving" and is appropriate for long-term storage and preservation of sets of files.
Originally, this was designed for archival storage on tape drives circa early s hence its name, Tape ARchive. Importantly, the TAR file format by itself doesn't handle compression. For this reason TAR files are almost always subsequently compressed with a pure compression method that isn't responsible for archiving.
Such methods, described below, by design do not record any archive information about the data being compressed, such as file names or sizes. In this sense, the TAR file's job is to archive group files and folders, while a compressor's job is to compress the resulting TAR file into a smaller file. This is done by compression methods that operate purely on a generic stream of data, and which do not record any archive information about the files contained within.
Applies Deflate compression to the file data, with some additional metadata. In common use but has some problems with the format specification. More information available at gzip. Applies BZIP2 compression to the file data, and includes metadata including built-in data integrity checks for each compressed block.
