Is NTFS or FAT32 more secure?

File system is a collection of algorithms and data structures that perform the translation from logical file operations to actual physical storage of information. In computing, a file system determines how data is stored and retrieved.

Without using the file system, information placed in a storage medium would be one large body of data with no way to know where one piece of information stops and the next one begins.
