文件系统的树状结构在每次创建一个新目录时,自动把. .和。目录项捆在一起。
The filesystem's tree structure, tied together with.. and. Entries, is built automatically each time you create a new directory.
在整个目录(树状结构),而不是单个文件中运行合并管理器,会让您意识到,该目录下的所有文件,哪些是添加的,删除的,或者修改的。
Running the merge manager on a whole directory (tree) instead of a single file will make you aware of all files in that directory that have been added, deleted, or modified.
这个作法在逐一查看大型目录树状结构时比较快,尽管处理时间相较于第一个范例可能会根据许多因素而不同。
This approach can be faster when you are iterating over large directory trees, although the processing time compared to the first example can depend on many factors.
