Scenario is that I have downloaded a ZIP file from internet. Now it's fully downloaded, but when I go to unzip that it shows error and stops unzipping.

Is there any app that can check the file and download only those part which are missing?

It is also like when we download same file with multiple links. In this scenario, user gives downloaded file and link to the file on internet.

    AFAIK that was called zipfix and (at least in the past) came along with the pkzip stuff. Not sure what it's nowadays on different OSes (you didn't specify yours, btw, and neither if you're willing to pay for the tool ;) On Linux, the zip command has the parameters -F | -FF | --fix | --fixfix for that purpose, by the way. – Izzy Mar 2 '16 at 8:00
  • @Izzy this command fixes the zip structure only , not the data in zip. – Vivek Ji Mar 2 '16 at 10:35

    Sure – and sorry, the "download missing parts" line escaped me as well. But how should such an app figure a) what parts are missing, and b) where to download them from? That would be the responsibility of the app you've used to download the file, not that of another app. – Izzy Mar 2 '16 at 12:55
  • As a partial solution I created a java app that unzips any corrupt zip files as much as it can : github.com/KYHSGeekCode/Unzip-Corrupt – KYHSGeekCode Oct 24 '18 at 11:12
