When the system needs to read from a hard disk drive (or other cached
peripheral) it actually reads more data than it needs and stores the
"extra" data in memory so that if a second read is required from the drive
it can get that information from memory, which is a far quicker operation.
This is a cache/buffer. Your program that is leaving the memory full at the
end is not a problem as when another program requires memory the old cache
information will be thrown away. (In theory ;->).
