Open a file only in a certain date
I have some data in Excel that I have saved as a CSV file. But I want that file to be allowed to be opened only from a certain date on. Is there anyway of doing that?
I'm not an expert on security of files like this. My sense, though, is that CSV files are among the most basic of text-based files, and they can be opened pretty much at will by just about any program.
So unless there's a way to surround it with some other shell file format (ZIP?) that contains an unlock date....unless there's something along those lines, the way to accomplish your objective without fail is to not distribute it until that certain date.
