are supported: *.tar.gz , *.tgz, *.tar, *.gz and *.zip.

Basic settings

Use archive name as root directory

Select this check box to create a folder named as the archive, if
it does not exist, under the specified directory and extract the
zipped file(s) to that folder.

Check the integrity before unzip

Select this check box to run an integrity check before unzipping
the archive.

Extract file paths

Select this check box to reproduce the file path structure zipped
in the archive.

Need a password

Select this check box and provide the correct password if the
archive to be unzipped is password protected. Note that the
