📄 File Information

The inf command displays the following information for files:

• File Name
• File Type
• File Size
• Created Time
• Modified Time

🔍 Duplicate Detection

Dark FS uses SHA-256 hashing to detect duplicate files.

Process:

File → SHA-256 Hash
File → SHA-256 Hash

Same Hash = Duplicate File

This approach is much more reliable than comparing only file names or file sizes.
