sir i uploaded a zip file. how i can unzip it now (any plugins). please give me options

You want to know how to unzip a file?

There's an option in the cpanel (i.e., if your host is using cpanel) to extract zipped files. You might want to go to the file manager and look for the "extract button" after selecting the zipped file. Or alternatively, you can extract the file first locally with your favorite archiver (such as winrar) then upload it into your server.
