读取文件的方式是知道文件名，直接读取的，不用遍历文件夹。
还想知道Linux系统的呢？

1.windows下最大文件数量与正在使用的文件系统有关详细
2.读取效率的话，操作系统将目录文件都是索引存放的，与mysql主键查找同个道理，影响不是太大，但肯定是数据越多，速度越慢。
3.linux我用的是centos系统，其他我不知道，文件系统管理受两个限制，磁盘空间和inode容量。就是说linux下文件的元信息（文件名，作者，创建时间）存放在inode里，有次我遇到过磁盘空间占用12%，但出现磁盘拒绝访问的情况，查了结果是没定期清理tmp目录导致小文件过多，导致inode下容量耗完。而inode的容量可以在分区的时候手动设定，一般指导
