Destroy 

compressed 

files that could 

not be 

decompressed 

Note: When you select this option, the ZyWALL deletes ZIP files 

that use password encryption.

Select this check box to have the ZyWALL delete any ZIP files that it 
is not able to unzip. The ZyWALL cannot unzip password protected 
ZIP files or a ZIP file within another ZIP file. There are also limits to 
the number of ZIP files that the ZyWALL can concurrently unzip. 

Note: The ZyWALL’s firmware package cannot go through the 

ZyWALL with this option enabled. The ZyWALL classifies 
the firmware package as not being able to be 
decompressed and deletes it. 

You can upload the firmware package to the ZyWALL with the option 
enabled, so you only need to clear this option while you download 
the firmware package.
