How can we wipe a folder permanently?For files I overwrite the file's contents using "85" as a char value, so it overwrites files with 01010101 bits.But I don't understand how I can overwrite folders' information/folders' names to permanently wipe the folders' names/information.Do folders have any contents other than files inside of them?How can I delete folders' names/information permanently(in a non-recoverable way) using standard C++(or C++ builder)? I use Windows 7.
