Why does my flash drive not have enough space when it DOES!? I am trying to copy a folder that contains an .iso to install a program. When I right-click the program folder, the properties tab says that size=4.0 GB. When I right-click my flash drive, the properties tab says free space=7.97 GB When I go to copy and paste the program folder from my Hard Drive to my flash drive it says there is not enough free space. ???!!!???!!! What the hell gives? Thanks!!
