1. Folder encryption feature added.

• The extension of the encrypted file is .enc.
• The extension of the encrypted folder is .encx.

2. Percentage progress bar added for the encryption process of large files and folders.

3. Coloring was done on the console screen.

• Red color in case of error in the process result
• Green color in case of successful process result

4. Encryption operations are restricted on the C:\ disk regardless of the folder or file.

• The purpose of this restriction is to prevent novice users from accidentally encrypting folders and files used by the operating system.
• Encryption and decryption operations can be performed in the main directory of the C:\ disk, but encryption operations are blocked by the program in folders used by the operating system and other folders and files in those folders.

These paths are:

• C:\Windows
• C:\Windows\System32
• C:\Program Files
• C:\Program Files (x86)
• C:\Users
• C:\ProgramData
• C:\$RECYCLE.BIN
• C:\System Volume Information
• C:\Users\<Username>\AppData
• C:\Users\<Username>\Documents

The folder paths that the program allows to encrypt on the C:\ disk are:

• C:\Users\<Username>\Downloads
• C:\Users\<Username>\Desktop

Apart from these directories, all kinds of encryption operations can be performed on other disks such as D:\ - E:\ - F:\ etc.
