A compressed file – upon decompression – must meet the specified limit.
Example: You set the limit to 20MB.
Scenario 1: If the size of archive.zip upon decompression is 30MB, none of the files contained in archive.zip will be scanned. The other two rules are no longer checked.
Scenario 2: If the size of my_archive.zip upon decompression is 10MB:
  • If my_archive.zip does not contain compressed files, Trend Micro Apex One skips Rule 2 and proceeds to Rule 3.
  • If my_archive.zip contains compressed files, the size of all decompressed files must be within the limit. For example, if my_archive.zip contains AAA.rar, BBB.zip and EEE.zip, and EEE.zip contains 222.zip:
    my_archive.zip
    		    
    = 10MB upon decompression
     
    \AAA.rar
    		  
    = 25MB upon decompression
     
    \BBB.zip
    		  
    = 3MB upon decompression
     
    \EEE.zip
    		  
    = 1MB upon decompression
       
    \222.zip
    = 2MB upon decompression
    my_archive.zip, BBB.zip, EEE.zip, and 222.zip will be checked against Rule 2 because the combined size of these files is within the 20MB limit. AAA.rar is skipped.
