HOW TO CONVERT USB FLASH DRIVE FROM FAT32 TO NTFS

You may try to copy some large files from system to the flash drive. But in that case it shows that "the file is too large for the destination file system" 
See for example:
if you want to copy a file that is more than 4GB,it just shows a warning below...stating that "file size>4GB...FAT32 error..."
