技术领域technical field
本发明实施例涉及计算机技术领域，特别是涉及一种清除设备使用痕迹的方法和装置。The embodiments of the present invention relate to the technical field of computers, and in particular, to a method and device for removing traces of equipment usage.
背景技术Background technique
随着时代的发展，越来越多的存储设备被人们广泛使用，比如U盘，移动硬盘，手机，数码相机等等。这些存储设备通过USB接口与电脑连接后，会在用户电脑系统中留下使用痕迹，当存储设备与电脑断开连接后，这些痕迹依然存在。因此，若要彻底清除存储设备在电脑上的所有使用痕迹，则需要对系统中遗留的信息进行清除。With the development of the times, more and more storage devices are widely used by people, such as U disk, mobile hard disk, mobile phone, digital camera and so on. After these storage devices are connected to the computer through the USB interface, they will leave traces of use in the user's computer system. When the storage device is disconnected from the computer, these traces still exist. Therefore, if you want to completely remove all traces of using the storage device on the computer, you need to remove the information left in the system.
以上现有技术中存在的问题是，实际情况中，电脑上可能连接过多个存储设备，用户可能只需要删除部分存储设备的使用痕迹，例如某个时期内或是某个品牌的存储设备，而大多用户对系统的结构并不了解，因此，无法区分出哪些遗留信息需要删除，进而无法做到选择性的删除使用痕迹。The problem existing in the above existing technologies is that in actual situations, multiple storage devices may be connected to the computer, and the user may only need to delete the usage traces of some storage devices, such as storage devices of a certain period or a certain brand, However, most users do not understand the structure of the system, so it is impossible to distinguish which legacy information needs to be deleted, and then it is impossible to selectively delete usage traces.
