Perplexing mismatch between properties of folder and its backup
I'm running 64-bit Windows 10 version 1803 on my ASUS X750JA laptop. Recently, I've noticed that after backing up files, the Windows Explorer 'Properties' for original and backup folders are quite different.
Today, for example, I copied the folder containing all my documents (i.e. not audio, photo or video files) from the D partition of my SSD to a USB stick, both NTFS formatted.
'Properties' for the original folder (on SSD):
Size: 9.52 GB (10,229,272,784 bytes)
Size on disk: 9.56 GB (10,272,018,432 bytes)
Contains: 19,916 Files, 1,977 Folders
Properties for the backup folder (simply created by copying and pasting the original folder to the USB stick):
Size: 9.52 GB (10,229,114,630 bytes)
Size on disk: 9.53 GB (10,236,719,104 bytes)
Contains: 19,897 Files, 1,977 Folders
How can there be such a large discrepancy (19 files and 35,299,328 bytes)?
Surely there should be no difference. That's the way it used to be. Please explain
