FileUtil.fullyDeleteContents介绍

[英]Delete the contents of a directory, not the directory itself. If we return false, the directory may be partially-deleted. If dir is a symlink to a directory, all the contents of the actual directory pointed to by dir will be deleted.
[中]删除目录的内容，而不是目录本身。如果返回false，则目录可能会被部分删除。如果dir是指向目录的符号链接，则dir指向的实际目录的所有内容都将被删除。
