How to recover corrupt zip files

Question

A user asked if l can help with zip files which he couldnt open on his PC, l tried to open it the normal way on both windows and linux(mint) but failed.

Is there any other not costly way of doing this?

Comments

l managed to use linux to recover the zipped files, unzip is native on linux, l ran #zip -FF (name-of-corrupt-folder.zip) --out new-folder.zip

Although it was giving errors, all was fine.
