Cannot copy large files to USB that still has free space

ex: Situation:
I have a game installer about 5gig of file size.
My flash drive has 8gig of free space and newly formatted.

Problem:
I cannot copy large files such as ISO files in to my usb/flash/pen drive/disk even if my usb drive still has large free space available. It keeps saying "DISK MEMORY FULL".

1st Possible Solution:
**WARNING** this will erase all of your files in your usb drive. Format your computer by doing right click on your drive then choose format. A new box will pop-up check quick format on format options. Wait for it to finish.

Explanation: Maybe your USB has viruses inside it that is eating up the memory space.

2nd Possible Solution:
Formatting your USB this way. This kind of formatting will not erase any files inside your USB.
On windows RUN command type "CONVERT X: /FS:NTFS" where X is the drive letter of your USB. A box will Pop-up with writing on it wait for it to finish or close it self.
You can now copy large files on your USB drive.

Explanation:
2 kinds of format on drive:
1. FAT32
2. NTFS
Most USB are FAT32 on default format. FAT32 has a limit of 4gig file size. That's why you will format your USB using this "CONVERT X: /FS:NTFS" to convert it to NTFS which can handle very large files.

  1. Actually, these 2 are the only solutions if we are getting similar kind of problem. If still your problem has not been solved then must be there is some defect in USB drive.

  2. This is probably due to the fact that most flash drives are formatted with the FAT32 file-system. A limit of FAT32 is that the largest any single file can be is around 4.2 gigabytes. For example, you cannot copy a 10 gig file to a 16 gig flash drive. NOT because it wouldn't fit on the drive but because the file-system cannot handle a file of that size. I hope this helps.
