It would be very great to have a <b>fileExists</b> command that returns a boolean based on if a specific file exists.
It is currently possible to check for a file by doing if (loadFile "path" != ""), however this produces a "Script xxx not found" message for the user if it doesn't exist, which can be somewhat of an annoyance.
Such a function would be very useful for checking if users have known cheating scripts in their Arma folder, or for instance checking if the text provided in the "picture" property of a CfgVehicles entry does indeed resolve to a file before attempting to display it.
