Files within the specified number of layers will be flagged for scanning.
For example:
| my_archive.zip | |||
| \BBB.zip | \CCC.xls | ||
| \DDD.txt | |||
| \EEE.zip | \111.pdf | ||
| \222.zip | \333.txt |
If you set the limit to two layers:
Apex One will ignore 333.txt because it is located on the third layer.
Apex One will flag the following files for scanning and then check Rule 3:
DDD.txt (located on the first layer)
CCC.xls (located on the second layer)
111.pdf (located on the second layer)
