Is there a Julia command that is the equivalent of `tar` on linux?

I have alot of small files and I want to group them into one file. I know tar does it. But I need to support Windows. Is there a Julia function that does the same as tar? And can untar a file?

You can use ZipFile.jl to create .zip archives, with or without compression. (There are also lots of alternatives to using lots of small files for storing collections of data.)
