Interestingly, I grabbed a completely empty 64GB thumb drive and only placed the OSMTiles on it.
I experimented with formatting, dragging and dropping the same directory as the only thing on the drive after each format:

Formatted as Fat32:    
   95.4 MB, size on disk 581 MB, Disk Properties disk space used: 316 MB
Format exFAT  (4k Allocations)
   95.4 MB, size on disk 581 MB, Disk Properties disk space used:
Format exFAT  (16k Allocations)
   95.4 MB, size on disk 581 MB, Disk Properties disk space used:

Format NTFS  (4k Allocations)
   95.4 MB, size on disk 581 MB, Disk Properties disk space used: 245 MB
Format NTFS  (256b Allocations)
   95.4 MB, size on disk 581 MB, Disk Properties disk space used: 229 MB

It appears the Windows directory properties reporting system is reporting differently than the actual used disk space.

On my Windows 7 laptop's hard drive (SSD) it reports
   95.4 MB, size on disk 136 MB, Disk Properties disk space used:

Note that if the SD card is 8GB or less the cluster size is 4kb .
If over 8, then the cluster size is 32 kb. So if you moved your
tiles to an 8GB card, it might just fit.
