From the SciTE4AutoIt3 help (under Extra Utilities --> AutoIt3Wrapper)...
Adding a file:
Files are stored in the RT_RCDATA section and are usually stored byte
for byte. If the section value is set to -10 (RT_RCDATA is internally
evaluated as 10) then the file is compressed before being added:
#AutoIt3Wrapper_Res_File_Add=file_name, RT_RCDATA : UNCOMPRESSED
#AutoIt3Wrapper_Res_File_Add=file_name, 10 ; UNCOMPRESSED
#AutoIt3Wrapper_Res_File_Add=file_name, -10 ; COMPRESSED
When the file is required it can be extracted using this code. Set the
$isCompressed parameter to match the Res_File_Add directive:
#include <WinAPIRes.au3>
#include <WinAPIInternals.au3>
