too much file size?

I've noticed something: when I use 'view info' on files on my usb memory stick, the file size is much bigger than when I use it on the same file on the desktop.

For example: I've got a gif file on my memory stick. Using 'view info' on that file it says:
Size: 32 KB on drive (7.129 bytes)

When I copy that same file on my desktop it says:
Size: 8 KB on drive (7.129 bytes)

Which makes more sense.

Why does it give 32 KB for a 7.129 bytes file when I vied the info on that file on a usb memory stick? It does that with all files on usb drives. The 7.129 bytes in this case seems to be the true file size, but for some reason 'view info' adds a significant file size to it. Can anyone explain this?

I think it will take more info.

Your Mac is _____
Formatted as ______
Memory stick formatted as _____

Maybe has something to do with 32-bit vs. 64-bit ??

The real filesize will (and should) remain intact regardless of where the file is stored, but the value of "KB on drive" will change since different filesystems and drives will use differing number of sectors to identify the same information.

The flash drive is usually FAT32 and your Mac uses HFS..so don't sweat the difference as long as the file size (in paren) matches across the two locations..

I would get more technical..but then that'd probably just confuse the issue..
