The actual disk space occupied by files depends on the file system. The maximum file size of the file system depends on the number of bits of reserved storage size information and the total size of the file system. For example, in the FAT32 file system, the size of a single file cannot exceed 4GiB. Some common file size units are:
1byte=8bits
1KiB=1,024bytes
1MiB=1,048,576bytes
1GiB=1,073,741,824bytes
1TiB=1,099,511,627,776bytes
