Comand line problems

Hello there. I'm trying to erase files usig Eraser through CMD. Could someone tell me what do i need to write in CMD to Erase, for example: all .txt files from "D:\test" directory?
Tried :
"C:\Program Files\Eraser\Eraser.exe" erase -folders "D:\test" -include="*.txt" -keepfolder -passes=35
And different variations of using -include: with ", without ", with = and without. It works, but erasing all the files in directory not only .txt.
