Unzip Files on iPad Pro

If you have downloaded a zip file/folder and don't get the option to unzip it on iPad

Then just tap and hold the zip file or a folder 

And then drag the zip file into "On my iPad" folder

Again, in "On my iPad" folder tap and hold the moved zip file

Now you will get the option to Uncompress the zip file at the bottom

So, the trick is to move the zip file to "on my iPad" to unzip it

To compress the unzip file again just tap & hold the uncompressed folder

And, tap on "compress" to zip it again
