why U disk cannot store 4G file? May 31, 2018

Currently 8G U disk has become the mainstream, 16G, 32G, 64G capacity is also very common in the market, but U disk is usually formatted as FAT32 file format, resulting in the partition's largest storage file size is 4G, into the beyond 4G file will be wrong. So you need to change the U disk file format to NTFS format.

why U disk cannot store 4G file?

How to safely convert U disk Fat32 format to NTFS? The following is the actual operation. Before the conversion, it is recommended to back up important data on the U disk first, just in case.

1. Change the USB file system to NTFS format

This is the easiest 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 file. If the file is too large or the number is large, the conversion process will continue for several minutes. If the drive is empty, the conversion process is faster because the computer temporarily moves these files to different locations.

Perform the following steps to convert the drive file format:

Connect the USB drive to your 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 while performing the above step 3, you can execute the command: CHKDSK U: /F and try again to execute the conversion command. The user can verify the converted file system by viewing the properties of the drive in "My Documents". Try to copy more than 4GB files or change file attributes to verify that the conversion process was successful.

2. Format USB to NTFS file system

Formatting a USB drive is much faster than converting its file format, but the files on the drive are all lost. It is best to choose this method when the USB drive is just purchased. However, some USB drives have stored some resources or tools when they were just purchased, and these should be protected when converting formats.

Perform the following steps to format:

Connect the USB drive to your 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" appears, you can change the settings in "Drive management" in the properties of the drive. Under "Disk Drives", change to "Optimize for performance" in the properties policy page of the USB drive.

Care must be taken when converting the USB drive file system. Before starting the conversion, you should weigh the advantages of using the FAT32 format, back up important data, and need to consider compatibility issues with non-Windows operating systems.
