Set permissions on files or folders (Windows XP, Windows 2000)

To set permissions on individual files and on folders, you must use NTFS file system.
NTFS file system provides features such as: Encrypt files, Compress a file or folder, Disk quotas and Set permissions on files or folders.
To convert a drive (for example drive C) to NTFS go to command prompt and type>> convert C: /fs:ntfs
Note that you cannot simply convert it back to FAT or FAT32.
OK, enough
