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
