[x_SCOTTiE_x]

how can i remove 1 line from a text document without opening it

could you please explain what your trying to do? I'm totally lost with this question, maybe if I understood, I could help, not being rude or anything, I just want to help you, I just don't understand.

edit: you mean to remove a sentence in a notepad .txt file without even opening it up ?
