R help - Mar 2017 - Unzip multiple layer of compressed (zip/tar) file

Hi, 

In a folder , there are multiple compressed (zip+tar) files. Each of compressed
file can have multiple layer of  compression (compressed file inside the
compressed file and so on).

Can anyone suggest, is there any way to decompress all the files in a single
directory ?
