每当从您的计算机中删除文件时，它们都是不受欢迎的，敏感数据可能会保留在您的硬盘或外部驱动器上。这可能会影响您的 Windows 10 计算机的安全和隐私。Overwrite是一款免费的Windows软件，它可以覆盖数据和元数据以及磁盘上的空白空间，从而使数据变得无法恢复。

您会看到，该程序使用-dirs和-data参数相对容易地覆盖文件名和其他内容。它写入一个小文件和一个大文件，并以这种方式覆盖Data Remanence。我们喜欢这样一个事实，即可以在擦除过程开始之前指定数据量以及文件数量。从我们目前看到的情况来看，该程序非常擅长擦除文件而不覆盖硬盘驱动器上的其他区域。

适用于 Windows 系统的覆盖工具

使用这个覆盖^(Overwrite)工具非常简单，因为大部分工作都是在一个窗口中完成的，这就是我们喜欢的东西。我们将介绍此工具的以下功能：

1. 元数据和数据
2. 数据单元和数据内容
3. 块大小
4. 覆盖
5. 其他特性。

让我们更详细地讨论这个问题。

擦除^(Erase)和覆盖^(overwrite)磁盘上的数据、元数据和空白空间

1]元数据和数据^{(1] Metadata and Data)}

用户首先会看到选项，前两个是Metadata和Data。从下拉菜单中，选择适合您需要的选项。元数据^(Metadata)从 10 开始，最高可达 1,000。

至于Data，它也从 10 开始，可以一直到 1,000，或者 All 如果你想要的话。

2] 数据单元和数据内容^{(2] Data Unit and Data Content)}

在单击Overwrite按钮之前，我们建议选择正确的Data Unit。这可以是兆字节^(Megabytes)或千兆字节。至于数据内容^{(Data Content)}，用户可以从零^(Zero)、一或随机^(Random)中进行选择。

3]块大小^{(3] Block Size)}

接下来，您可能想要更改块大小或保持原样。有五个选项可供选择，因此请选择最适合您需求的选项。

4]覆盖^{(4] Overwrite)}

最后，您将要单击“覆盖^(Overwrite)”按钮以开始该过程。不会花很长时间，但这完全取决于您的计算机速度和需要覆盖的文件数量。

5]其他功能^{(5] Other features)}

1. 它是安全的，不会覆盖现有文件，并使用操作系统功能进行覆盖。
2. 可用于不同的文件系统，如NTFS UFS EXT FAT
3. 适用于  Windows、Linux、Unix等操作系统。
4. 可以指定不同的选项，如块大小、文件数和数据量。
5. 它是免费和开源的，具有一般公共许可证。

Erase, wipe & overwrite data, metadata & empty space on disk

Whenever files are deleted from your computer, thеy are just unliked and the sensitive data could remain on your hard disk or external drive. That is sоmething that could affect security and privacy where your Windows 10 comрuter is concerned. Overwrite is a free Windows software that overwrites data & metadata, as well as the empty space on your disk so that the data becomes irretrievable.

You see, the program uses -dirs and -data parameters to overwrite file names and other content with relative ease. It writes small files and one big file, and in this way overwrites Data Remanence.  We like the fact that the quantity of data, along with the number of files, can be specified before the beginning of the erasing process. From what we have seen so far, the program is pretty good at erasing files without overwriting other areas on the hard drive.

Overwrite tool for Windows systems

Using this Overwrite tool is very simple because everything is done from a single window for the most part, and that’s something we’ve come to enjoy. We will cover the following functions of this tool:

1. Metadata and Data
2. Data Unit and Data Content
3. Block Size
4. Overwrite
5. Other features.

Let us talk about this in more detail.

Erase & overwrite data, metadata & empty space on disk

1] Metadata and Data

The first things users will see are the options, and the first two are Metadata and Data. From the drop-down menu, select the options that are reasonable to your needs. Metadata starts at 10 and can go all the way up to 1,000.

As for Data, it begins at 10 also and can go all the way up to 1,000, or All if that’s what you want.

2] Data Unit and Data Content

Before clicking the Overwrite button, we suggest selecting the right Data Unit. This can either be in Megabytes, or Gigabytes. As for Data Content, the user can select from Zero, One, or Random.

3] Block Size

Next up, you might want to change the block size or leave it as is. There are five options to choose from, so select the ones that best suit your needs.

4] Overwrite

Finally, you will want to click on the Overwrite button to start the process. It won’t take long, though it all depends on the speed of your computer and the number of files that needs to be overwritten.

5] Other features

1. It is safe, does not overwrite existing files, and uses operating system functions for overwriting.
2. Can be used on different file systems like NTFS UFS EXT FAT
3. Works on operating systems like  Windows, Linux, Unix.
4. Different options can be specified, as block size, the number of files & quantity of data.
5. It is free and open-source with a general public license.
