This can help or hurt, depending on how it's utilized. When a file is written, it will actually consume a multiple of your allocation unit size. You'll need to format it to NTFS to copy individual files > 4GB.Īn allocation unit can be thought of as a 'chunk' of storage space. You'll get the 'file too large' message when copying a 7GB file if the target drive is formatted FAT32. You could save a little space by formatting it FAT32, but you of course have the limitations of FAT32, like maximum individual file size of 4GB, and you'll have a 32kb sector size which creates a lot of slack space if you have a high number of files, but sometimes it's a trade worth having.Īs soon as i bought Flash i connected it to my laptop tried to copy two 7 gb files but i had a message that informed me that the file is too big,that was disappointing cos i though that using flash drive is a piece of cake anyway i googled my problem and yea i found out that it can be formatted.im mostly going to use this fd for copying big files from laptop which is almost full to my pc these files are iso 7 gb and i cant copy them to simple dvd so this fd is great and fast way to do it(not related to my main question>i also bought usb to usb cable tried to glue laptop and pc that is working only in safe mode due to some problem but that cable didnt work maybe safe mode causing this prob,before that i tried Dual layer dvd to save my huge music programs but i bought not Verbatim DL dvd but cheap and i have error and my dvd drive cant burn it correctly at least Flash Drive works fine ) 14.6 sounds about for a NTFS formatted 16gb drive. Welcome to the world of formatted capacities.
