ArchiDroid unpacks zips, rars, and many other formats

Most built-in file managers can unpack zip files, but you'll need non-stock apps to extract other formats like rar, 7zip, etc.

File manager ES File Explorer unwraps zips and rars, File Expert opens zip, rar, tar, gzip and a few other formats. AndroZip extracts zip, rar, tar, gzip, bzip, and 7zip. All of them can create zips too.

New kid on the block ArchiDroid unpacks zip, rar, tar, gzip, bzip2, and 7zip. It also opens password protected zips and rars. What really makes it stand out is that it knows how to deal with split rar archives. Of course it can make zips, including encrypted zip archives.

ArchiDroid is free, it doesn't have ads, and it doesn't ask for permission to go online.
