如果你在查看的时候，使用了“缩略图”视图，或者以幻灯片方式，那么就会在那个的文件下产生一 Thumbdb 的文件。这个文件是隐藏的（系统用来缓存你浏览过的缩略图）。

这些文件留着一点也不影响使用，你可以放心删掉它们，但是以后预览好缩略图后，Thumbdb 文件还会出现。这种是默认状态，如果不想让这些 Thumbdb 文件自动生成，你可以在文件夹选项里把他们关掉。（Windows XP 上的步骤：工具 -> 文件夹选项 -> 不缓存缩略图勾上）

如果你想一次性全删除的话，使用360安全卫士的清理垃圾，勾选上“缩略图缓存文件”。或者是windows优化大师等软件清理一下垃圾文件。

大熊猫是一种有着独特黑白相间毛色的活泼动物。它的拉丁名：Ailuropoda melanoleuca，指的就是它黑白相间的外表。大熊猫的种属是一个争论了一个世纪的问题，最近的DNA分析表明，现在国际上普遍接受将它列为熊科、大熊猫亚科的分类方法，目前也逐步得到国内的认可。国内传统分类将大熊猫单列为大熊猫科。它代表了熊科的早期分支。成年熊猫长约120~190厘米，体重85到125公斤。独特的特征包括：大而平的臼齿，它的一根腕骨已经发育成了“伪拇指”这都是为了适应以竹子为食的生活。与其他六种熊类不同，大熊猫和太阳熊都没有冬眠行为。大熊猫的祖先是始熊猫（Ailuaractos lufengensis），这是一种由拟熊类演变而成的以食肉为主的最早的熊猫。始熊猫的主枝则在中国的中部和南部继续演化，其中一种在距今约300万年的更新世初期出现，体形比现在的熊猫小，从牙齿推断它已进化成为兼食竹类的杂食兽，此后这一主支向亚热带扩展，分布广泛，在华北、西北、华东、西南、华南以至越南和缅甸北部都发现了化石。在这一过程中，大熊猫适应了亚热带竹林生活，体型逐渐增大，依赖竹子为生。在距今50-70万年的更新世中、晚期是大熊猫的鼎盛时期。现在的大熊猫的臼齿发达，爪子除了五趾外还有一个“拇指”。这个“拇指”其实是一节腕骨特化形成，学名叫做“桡侧籽骨”，主要起握住竹子的作用。
