Java implementation Simple File Manipulation tool class

This article introduces a simple tool class for file operations, including folder creation, folder deletion, file creation, file renaming, file copying, and file Deletion. If you need to copy a folder, you are actually creating the folder and copying the Files. Directly below the code

The general process of file operation is this way, as to the details, the form of parameters, check, return type and other issues can be adjusted according to the needs of the Perfect.
