# The maximum depth to which zip archives will be unpacked, to allow for
# checking filenames and filetypes within zip archives.
#
# Note: This setting does *not* affect virus scanning in archives at all.
#
# To disable this feature set this to 0.
# A common useful setting is this option = 0, and Allow Password-Protected
# Archives = no. That block password-protected archives but does not do
# any filename/filetype checks on the files within the archive.
# This can also be the filename of a ruleset.
Maximum Archive Depth = 0
