FormIt and .exe

I can not figure out how to get the FormIt is loaded exe files. In all settings, specify the format of a valid, but the hook if the extension = exe, $ _FILES array goes blank. In this case the image is loaded properly

You want to allow .EXE files to be uploaded using FormIt?

You will need to allow that extension as a permissible file type in System Settings. The key you want is

But I have already done so, see screenshot

Maybe this will help: modX revo 2.2.2, formit 2.0.3

Trivial point, but it's usually case sensitive, so you'll want exe and EXE.

Also check that the max-upload setting on both PHP and in MODX allow files of the size you want uploaded.

I can't remember doing this with FormIt, but you could maybe try FileUploader instead:
