The display size of my hard disk doesn't match the file size I saved? !

Please study the operating system course ... Because of the current storage mode of the file system, the system will use more capacity than the actual size of the file ... The more files, the more hard disk clusters will be occupied. Similarly, the more file fragments, the more space it takes up. As the security management of file permissions, ntfs format will divide more space than fat32 format. ......

If you don't have time to study the operating system course, just look at the file storage format in the microcomputer and the contents of the storage management at the bottom of the hard disk. .....
