I would try to do this the right way in stead of hacking it.
Create a zip file with 10+ files (Docs, PDF's not excle or comma files)
Upload that to the IDM profile.. make sure to check the box to 'Create Profile on Save"
Create a policy then to detect against that IDM and set the % to a low number (5 or 10%)
Then create an incident by copying a bunch of lines from one of the files and putting in an email or copying a portion of the file to USB.
Good Luck, Ronak.
