I have used this library, however it's straight forward to remove the password from the zip file.  

What is the best method to remove the password off the files within the zip file?

Is it possible to remove the password of the files within the WinZip file (ZipFile.entries) without having to extract (ExtractWithPassword), remove entry and reimport each file within the selected archive file?

>Is it possible to remove the password of the files

Office files? No. Because you need to open those files to remove the password.

In that case which method can I use to determine if the file/zip entry individually does have a password?
