Why a USB flash drive can only store files below 4G

Now the capacity of the U disk is getting bigger, 8G has become the mainstream, 16G, 32G These are no longer what strange things, but the U disk will usually be formatted as FAT32 file format, which will cause the disk partition of the maximum file volume limit to 4G, more than 4G will appear error. So you need to change the USB drive file format to NTFS format.

How to convert the USB flash drive Fat32 format to NTFS? Let's do it with you now. It is recommended that you back up the important data on the USB flash drive before conversion, just in case.

1. Change the USB file system to NTFS format

This is the simplest way to change the file format on a USB drive, especially if the file system exists. Using this method to transform the file system does not delete the existing files. If the size of the file is larger or more numerous, the conversion process lasts a few minutes. If the drive is empty, the conversion process is faster because the computer temporarily moves the files to a different location.

Perform the following steps to convert the drive file format:

Connect the USB drive to the computer and assign it a drive letter

Click Start > Programs > Accessories

In the Run Command field, enter: CONVERT F:/fs:ntfs (f is your USB drive letter).

If you get an error message when you perform the 3rd step above, you can execute the command: CHKDSK U:/F, and then try to execute the conversion command again. The user can verify the converted file system by looking at the properties of the drive in My Documents. Try copying more than 4GB files or changing file attributes to verify that the conversion process was successful.

2. Format USB as the NTFS file system

Formatting a USB drive is much faster than converting its file format, but the files on that drive are all lost. It is best to select this method when the USB drive is just purchased. But there are also USB drives that have been stored with some resources or tools at the time of purchase and should be protected when converting the format.

Perform the following steps to format:

Connect the USB drive to the computer and assign it a drive letter

Click Start > Programs > Accessories

In the Run Command field, enter: FORMAT U:/fs:ntfs (U is your USB drive letter)

If the error message "There is no NTFS support on the USB drive", you can change the settings in the properties of the drive "drive management". Under disk drives, in the Properties policy page of the USB drive, change to "optimize for performance."

Care must be taken in the process of converting a USB drive file system. Before you start the conversion, you should weigh the benefits of using the FAT32 format, back up your important data, and consider compatibility issues with non-Windows operating systems.
