推荐答案

您需要编写一些代码来扫描目录树并获取每个目录中每个文件的详细信息.您可以在程序开始时执行此操作，尽管这可能是非常耗时的任务.一种更好的方法(也是我已经实现的一种方法)是从仅包含系统上磁盘驱动器的树开始.然后，当用户单击磁盘时，您可以展开树以包括所有顶级目录.在扩展目录时重复此过程，您应该能够很快看到树的任何部分.当树折叠时，您可以根据需要丢弃或缓存数据.

You need to write some code to scan through your directory trees and get the details of each file in each directory. You can do this at the beginning of your program, although that can be a very time consuming task. A slightly better way (and one that I have implemented) is to start with the tree containing only the disk drives on your system. Then as the user clicks on a disk you can expand the tree to include all the top level directories. Repeat this process as directories are expanded and you should be able to see any part of the tree fairly quickly. When trees are collapsed you can discard or cache the data as required.
