Quote from mIRC 5.51 versions.txt:
134.Added $file(filename).size,.mtime identifier, .mtime returns a
$ctime value indicating when the file was last modified.

Note: $lof() is supported for now but will be removed in future.


$lof(filename) was replaced by $file(filename).size (although the .size isn't needed, it will return the file size without it). $lof was left in for compatability.
