How to delete content from a text file using windows batch script

Question

I have a demo.txt file. I need to delete content in that file using a batch file. Please tell me the command to delete content for demo.txt file.

Answer 1

type nul > demo.txt

works and also works in JPSoft's TakeCommand TCC.EXE command shell (where "break" will output "BREAK is ON" rather than nothing as it does in Microsoft CMD.EXE)

The general idea is to find a command that outputs Nothing and redirect that to the file using >
