Can't load zip file in 'Zip To PDF'

[haodi19]

In module 'ZIP to PDF', the app can not load the chosen zip file, instead it will raise an exception. Besides, during 'ZIP to PDF', the images in the zip file will be saved in a temp directory and will not be deleted after generating the PDF file, which will waste the disk memory.

Steps to reproduce

1. In 'ZIP to PDF' module, select a zip file and click button 'Convert To PDF'.

Expected behaviour

The zip file should be converted to a PDF file, and the images in the zip file should not be saved in disk after conversion.

Actual behaviour

Raise exception 'java.io.FileNotFoundException':

Also, the images will be saved on directory temp permanently (After solving the previous problem).
