Understanding Computers/copy/paste


I just did a large copy/paste from an external hard drive to a 32G flash drive.  I wouldn't be surprised to see less than the original get copied, but for the "size on disk" and number of files the reverse happened and I would like to understand the computer logic of that.  

So here is what I copied from the external hard drive, per the Properties:
Size: 23.7GB (25,538,642,482)
Size on disk: 24.0 GB (25,786,683,392)
109,321 Files, 5,526 Folders

Here is what shows on the flash drive after the job is completd:
Size:  23.7GB (25,543,915,440)
Size on disk:  24.8 GB (26,706,362,368)
109,330 Files, 5,526 Folders

Hello Art:
Thanks for asking this question.

Can you identify what extra files have been copied to flash drive?
I see there will be nine more files.
I think that those files could be Hidden system files in External.

Please try this.
