Now the USB flash drive is getting bigger and bigger, and 8 GB is very common (I am 8 GB ). When we buy such a large USB flash drive, we will inevitably want it to copy large files, such as HD videos and Hard Disk Images. However, I found that some USB flash drives cannot copy files larger than 4 GB. After some research, it is found that the failure to copy files larger than 4 GB is not a problem of the quality of the USB flash disk, but the file system is doing something strange. Currently, common file systems include NTFS, fat16, FAT32, ext2, and ext3 (Linux). Their supported partition sizes and single file sizes are:
NTFS (Windows): supports up to 2 TB of partitions and 2 TB of files.
Fat16 (Windows): supports a maximum partition of 2 GB and a maximum file of 2 GB.
FAT32 (Windows): supports a maximum partition of 128 GB and a maximum file of 4 GB.
HPFs (OS/2): supports a maximum of 2 TB partitions and a maximum of 2 GB files
Ext2 and ext3 (Linux): supports a maximum of 4 TB partitions and a maximum of 2 GB files.
JFS (Aix): supports a maximum partition of 4 P (block size = 4 K) and a maximum of 4 P
XFS (IRIX): A 64-bit file system that supports 9e (63 power of 2) partitioning.
Based on this theory, we can only convert the file system to NTFS to copy files larger than 4G!
