目标目标：
a）上传.zip文件，将其组件提取到我服务器上的临时目录中
b）在一个地方复制/移动所有文件，但唯一地重命名所有文件，以便没有两个文件具有相同的名称（在物理位置）
c）在db中开发逻辑文件夹树结构（注意复制时的文件夹名称并将其存储在db中，同时存储其内容文件，使得所有文件都具有其所属文件夹的父ID）
阐释：
压缩文件上传到common / uploads / directories / FolderName.zip，解压缩到common / uploads / directories / ExtractedArchive / FolderName，然后根据定义的文件规则验证每个文件，如果验证，则复制到位置common / uploads / files /
这些文件位于共享的物理位置，但在db中，它们以下面的方式连接（递归，无限深度）
再一次，所有文件都在服务器的同一目录中，但它们通过逻辑目录树结构相互连接。 这在db：
中变成如下所示fileId | filename | type | parent
1 | FolderName | folder | null
2 | File1.html | file | 1
3 | File2.txt | file | 1
4 | TestFolder | folder | 1
5 | File3.doc | file | 4
6 | file4.pdf | file | 4
7 | Another Test Folder | folder | 4
8 | docx file.docx | file | 7
9 | document file.pdf | file | 7
10 | file5.jpg | file | 4
依旧......

问题 上传结构未得到维护。我得到的结构以这样的方式出现，即父目录中的文件实际上属于其子目录模型。然而，子目录模型也是在没有内容的情况下创建的。一切都搞砸了。
我已经删除了这里没有使用的代码，因此您不必阅读不必要的代码来解决问题的底线;但是如果你需要查看我机器上的完整代码，请告诉我。
感谢任何帮助。先谢谢你们。 保持幸福。
