Users typically combine these two formats to solve specific limitations of each:
: The native .7z format often does not preserve Unix-style file permissions, ownership, or extended metadata. By first creating a .tar file, these attributes are locked in before compression. tar4.7z
A .tar.7z file is a created by first bundling multiple files into a single .tar (Tape Archive) file and then compressing that file using the 7-Zip ( .7z ) algorithm. This double-process is similar to the more common .tar.gz , but it uses the 7-Zip LZMA/LZMA2 method for potentially higher compression ratios. Why Use .tar.7z ?
