What is Thumbs.db?

博主发现电脑和Web服务器文件夹里的Thumbs.db文件,起初以为是病毒或黑客痕迹。实际它是Windows系统在以缩略图方式浏览含图片文件夹后生成的数据库文件,无害可安全删除。还给出关闭生成该文件特性的设置步骤。

         最近我在我的电脑和学校的Web服务器的许多文件夹里发现了一个神秘的文件,“Thumbs.db”,从名字上看,这个文件好象是病毒,我还猜想是黑客入侵后留下的痕迹。
        但是事实是这样的,Thumbs.db是无害的,它是由Windows操作系统产生的,怎么回产生这个文件呢,是由于在使用了“缩略图(thumbnail)”方式浏览了含有图片的文件夹后,系统生成的包含浏览过的图片的数据库文件,所以,可以安全的删除它,不需要有这样的备份,可以如下进行设置,关闭这个特性,节约空间:
1.点击“开始”
2。选择“控制面板”
3。选择“文件夹选项”
4。选择“查看”
5。勾选“不缓存缩略图”
6。点击“OK”
现在你可以搜索你电脑上的Thumbs.db文件,删除它们。
