***For Chrome OS Only*** Enable mounting of a variety of archive formats (and different compression schemes) in the Files.app just like the native ZIP/RAR support that exists today. Most notably, 7z & tarballs! Supported archive formats: 7z ar cab cpio deb iso pax rpm tar Supported compression formats: bzip2 gzip lzma xz Z Please be aware that the extraction performance is not optimal with these "streaming" archive formats because of the design of the file format itself. There is little that can be done in the extension when the file itself does not include an index. Whenever you want to extract a file, the whole archive must be scanned. The larger the archive file (and the # of files in it), the slower things will be. Source code can be found here: https://chromium.googlesource.com/apps/unpacker/
