So i got my 32 gig flash drive its sweet... but like the rest of my flashdrives that doesnt acculy hold the size it should, it only shows 29.4 gb ... does anyone know how to open all of it?

Like hard drives or other storage devices, the formatted capacity is always less than the listed value. This is because drive makers use 1KB = 1,000 bytes rather than 1024 bytes. Hence, there is actually less space available due to binary math.
