重庆大学11级计算机学院的第一个JAVA实验： In this project, you are required to implement a file manager on the command line. This manager should include the following functions: Create/Delete a directory. Enter a specified directory. List the files and directories in the current directory (you do not have to expand any sub-directory) sorted by name, date, size, type, etc. Rename/delete a specified file. Copy a specified file to another directory. Copy a specified directory (along with all sub-directories and files) to another directory. Encrypt/decrypt a specified file. Compress some files into a archive.(.zip or .jar ) and extract files. Cut a big files into some small files and merge some small files into the original file. The project can be exported to be a runnable jar file.
