MaxSize
Maximum unpacked size of archived files :
There are some archived files that have useless content but intentionally expand to an
"irrational size" when unpacked in order to slow down the computer. This parameter
avoids unpacking such archive files.
If the setting is 0, all archived files are unpacked, whatever their size.
If the set value is >0, all archives that do not exceed the given value (in bytes) are
unpacked and scanned.
e.g.: 2kB (2 Kilobytes), 3MB (3 Megabytes).
ArchiveMaxSize 0
ArchiveMax
Recursion
Maximum archive recursion :
If the setting is 0, recursive (nested) archives are unpacked, whatever their
recursion depth.
If the set value is >0, all archives that do not exceed the given recursion depth are
unpacked. This saves time.
ArchiveMaxRecursion 5
ArchiveMax
Ratio
Blocking "mail bombs" :
Blocks so-called "mail bombs" with a very high compression ratio. You can set the
maximum difference between packed and unpacked file size.
The zero value deactivates this option. This value is not recommended. The default
is 150.
ArchiveMaxRatio 150
