File path is always relative to mission directory. If script dir\a.sqf includes dir\b.sqf, use "dir\b.sqf" and not "b.sqf".

The main difference between preprocessFile and preprocessFileLineNumbers is that the latter adds #line directive to the target file, which allows to log the __LINE__ error happened at and the __FILE__ error happened in.

Essentially what the preprocessFile command does is it refers to the contents of a file as a string:
Example 1:
boop.html: 
<t align = 'center' valign = 'middle' shadow = '0' size = '2'>structured text</t>

init.sqf:

_text = parseText preprocessFile "boop.html"; hint _text;
This is especially useful for long strings, and it works on files with any file extension as long as they can be edited with a text editor.
Example 2:
init.sqf:
hint preprocessFile "description.ext"; copyToClipboard preprocessFile "mission.sqm";
The above is all valid. However, using *.jpg or any other files saved in an image format is not possible.
