i remove all files on the USB flash drive. the thumb drive has 6GB but when i try to copy a 4.61GB ISO file, it says the file is too large. the flash drive format is FAT32, can this be the problem?
No i think is because your flash drive i think your flash drive doesn't support larger files try to archive your file with winrar or other archiving program and that should do the work
The largest file a FAT32 drive can hold is 4GB. So you have to reformat the drive as NTFS. To do this:
1. Get all of your files off the flash drive.
2. Go to My Computer, right click the drive and click Format.
3. Under file system choose NTFS.
4. Format.
