If you are looking to Extract file on an FTP server, then here today we are going to a simple method to do so. If you have connected your remote server and have some files to extract it, then this guide will definitely help you. Follow our below steps to unzip a compressed file like .rar, zip, tar, etc.
A Simple way to Unzip the Compressed file on FTP Remote Server
Step 1: I suggest you install FileZilla and connect your remote server using Server IP address/Host, Username, Password & Port Number.
Step 2: Now Enter the public_html folder & head to the path where your compressed file exists.
Step 3: Now Create a file called on your Desktop/PC called unzipper.php and Copy paste the below code-
<?php /** * The Unzipper extracts .zip or .rar archives and .gz files on webservers. * It's handy if you do not have shell access.

Step 4: Now Upload the unzipper.php file on the folder where the .zip, .rar or .gz file located.
Step 5: Now visit the URL along with the filename called unzipper.php
Say Example: Your compressed file located on http://yourdomain.com/myfile/ then visit the URL http://yourdomain.com/myfile/unzipper.php
Then you will see the compressed file like below-
Click on Unzip Archive Button. It will give a successful message of the status.
Now reload your files to see the list of extracted files.
thank you. It been really helpful.
