　　有很多朋友都有一个问题，为什么删除的数据还可以恢复？经常会看到这样的新闻，某人去修电脑，结果电脑里删除的数据被恢复还被窃取了重要内容，那么为啥已经被删除的文件还能够被恢复呢？系统之家小编今天来通俗易懂地讲一讲，顺便说说如何进行数据恢复？

　　因为所谓的文件删除，只是删除用户打开这些软件的通道罢了，并不是真正的删除物理文件，相当于文件被做了一个“已删除”的标记罢了，往后新增的数据可以覆盖掉它们。只有新数据覆盖掉这些标记了“已删除”的区域，那么原来的数据才不能被恢复。

　　这么说应该比较容易懂吧。

　　由文件删除的原理可知，要彻底删除数据，只有把删除文件所在的数据区完全覆盖掉。绝大部分彻底删除工具所使用的就是这个道理：把无用的数据反复写入删除文件的数据区，并进行多次地覆盖，从而达到完全删除文件的目的。

　　Windows的这种伪删除，也给我们带来了好处，让我们有后悔药可吃。但对于很机密的文件就有了麻烦，存在着被重新恢复的可能性。所以，删除机密文件，一定要借助彻底删除工具，让机密文件彻底“粉身碎骨”，这样你就可以高枕无忧了。

　　有的朋友则是因为误操作把文件给删除了，那么想要进行数据恢复应该怎么做呢？

　　下载一款数据恢复软件，例如傲软数据恢复软件，网络上有很多这种功能的软件。

　　操作一般都不会很难，选择需要恢复数据的磁盘，点击开始扫描已删除的数据，最后再从中选择自己需要恢复的文件。

　　希望以上所说的内容可以帮助到大家，更多有关电脑系统操作的问题可以关注系统之家的相关频道。
