| 项目描述: |
Paranoia dictates that sometimes when we want a file deleted, we want it to stay deleted so that no one can remove our hard disks and find any magnetic remnents of files we have created and later deleted. Our government insists that three rewrites of the file are sufficient to destroy the image. ZapFile assumes the government standard is false and that it takes more to accomplish a total erasure of the file. ZapFile rewrites the file 100 times, saves it to disk each time, and finally deletes it. If this file can be accessed it should contain only chr(126) as readable characters. The original file is now forever erased and a disk reader will find only '~' characters on disk where the file used to be.. ′′
有些人规定，当我们需要删除一个文件时，这个文件在删除之后没有人可以移动我们的物理磁盘，并发现我们创建并随后删除的文件的任何磁界质遗迹。我们的政府坚持认为重写三次文件足以清除文件遗迹。ZapFile认为政府标准还不够正确，它进行更多次的有保证的重写。ZapFile会重写文件100次，每次都将其保存在磁盘上，最后在删除它。如果这个文件被访问，它只包含可读的字符chr(126)。原来的文件被永久删除，在磁盘上原文件处只留下'~'字符。
