We have all been in the situation where we have half-finished work due tomorrow. You can upload a unfinished word document and this tool will modify it so that it cannot be opened. You can send the corrupted file instead to buy yourself some extra time.
I’m guilty of doing this maybe a couple of times. But I never knew that such tool can do it easier. What I do is just change the file type to .doc of a file which is not really one.
