Hi, I need a simple routine in C# that takes in input a ZIP filename and it scrambles it. For "scramble" I mean that it overwrites a few bytes in the ZIP files so that Windows (and other programs) do not recognize it as a valid ZIP file. Here's the routine: void ScrambleZipFile (string fileName, bool scramble) { //WRITE CODE } If the "scramble" parameter is true, then the file is scrambled (so that it cannot be recognized as ZIP file); if the "scramble" parameter is false, then the file is restored (so that it be recognized as ZIP file again). I would call it this way: ScrambleZipFile (@"c:\[login to view URL]", true) Files can be very big, so do not read them in memory. Thanks.

My plan is to mess with the file header, so other program will not recognize it as a zip file. (do something to data of the file is also an option, but if the header is enough that should be the best solution)
