Is there a limit on INI file size?

I generated (and can read) an INI file that is 1.1 MB. Have no problem reading it, but when I try to enumerate the sections, I get an "expression too long!" error.

The code is:
Code:
 
$List = ReadProfileString('.\data.ini', '', '')


I'm thinking I may need to split this INI file into smaller parts.

Thanks

Glenn
