Directory_System

The computer OS uses an organizational unit called "directory" to organize the folder and files into a hierarchical structure. A directory contains multiple files and other directories and it provides user with a logical file group.

A directory uses "/" as a separator character and shows its route within the file system. "/" may represent a root directory or a hierarchical relationship between parent directories and subdirectories. For instance, "/aa/bb" indicates that under the root directory, there is the "aa" directory, beneath which lies the "bb" directory.

There are various features related to a directory but following 5 features are implemented in this project

  • Create a directory
  • Remove a directory
  • Copy a directory
  • Move a directory
  • Check the number of subdirectories



Look at the table below in which functions are called in following order



When functions #1 to #4 are called, the directory structure will be like this [Fig. 1]



When function #5 is called, the directory structure will be like this [Fig. 2]



When function #6 is called, the directory structure will be like this [Fig. 3]



When function #7 is called, the directory structure will be like this [Fig. 4]



When function #9 is called, the directory structure will be like this [Fig. 5]



Constraints

  • Maximum directories that can be made is 50,000
  • The directory name is made of small letters and its length is >=2 and <=6
  • The route of every directory is not longer than 1999
  • No directories under same parent have same name
  • Only upto 30 directories can have same parent directory


How to Compile and Run Project

  • git clone https://github.com/HarryAhuja/Directory_System.git
  • cd Directory_System/
  • make clean
  • make -j
  • ./directory.exe -->(directory is the name of executable)
  • Output of the program should be "#Test Case:1 Passed"
  • All Object files will be stored in Directory_System/output/ folder


Input

  • Input test file is in ./input/ folder
  • Input is given according to following functions index
  • 1: CMD_MKDIR
  • 2: CMD_RM
  • 3: CMD_CP
  • 4: CMD_MV
  • 5: CMD_FIND


Output

  • #Test Case Number : Passed/Failed
