Which of the following tasks is performed by the root directory in a computer system? 

📘 Explanation

The Root Directory is the top-most directory in a file system.
It acts as the main folder that contains all other folders (subdirectories) and files.

Its main function is:

👉 Organizing and storing files into separate folders (subdirectories) so that the file system remains structured.

The root directory helps in maintaining a hierarchical structure like:

C:\
 ├── Program Files
 ├── Users
 ├── Windows
 └── Documents

Other options are incorrect because:

❌ Locating files quickly – This is mainly done by the operating system and indexing system.
❌ Modifying file content – This is done by software applications.
❌ Creating new files – This is done by users or programs, not specifically by the root directory.

📗 व्याख्या

Root Directory फाइल सिस्टम की सबसे ऊपरी (top) डायरेक्टरी होती है।
यह मुख्य फ़ोल्डर होता है जिसके अंदर अन्य सभी फ़ोल्डर और फाइलें होती हैं।

इसका मुख्य कार्य है:

👉 फ़ाइलों को अलग-अलग फ़ोल्डरों (subdirectories) में व्यवस्थित रूप से स्टोर करना।

यह फाइल सिस्टम को व्यवस्थित (organized) बनाता है।

उदाहरण (Windows में):

C:\

यह C ड्राइव की Root Directory है।

• NTFS (Windows)
• FAT32
• ext4 (Linux)

🔹 Root directory does not have a parent directory.
रूट डायरेक्टरी की कोई parent directory नहीं होती।
