Use TfileUnarchive on Amazon S3

I have a talend job which is simple like below: ts3Connection -> ts3Get -> tfileinputDelimeted -> tmap -> tamazonmysqloutput.

Now the scenario here is that some times I get the file in .txt format and sometimes I get it in a zip file. So I want to use tFileUnarchive to unzip the file if it's in zip or process it bypassing the tFileUnarchive component if the file is in unzipped format i.e only in .txt format.

Any help on this is greatly appreciated.
