After you have purchased the thumb drive, you will find that the capacity of the thumb drive does not match the official capacity of the operating system. The capacity of the thumb drive in the operating system does not match the official capacity of the thumb drive. The capacity in the operating system is less than the official capacity of the hard drive. The larger the capacity, the greater the difference. As we all know, the binary algorithm used in computers is 1MB=1024KB; 1GB=1024MB, while the hard drive vendor's algorithm is 1MB=1000KB; 1GB=1000MB. So there is a discrepancy between the hard disk capacity displayed in the operating system and the nominal capacity. It is normal for the hard drive to have a difference of about 5%-10%

Actual capacity: 64GB = approximately 58GB - 59GB

Package: 1PCS flash drive, 1 titanium steel necklace

Warm tip:
Due to the special and different file systems, fat32 format u disk can only copy or create a single file not larger than 4g, however, ntfs format can support the creation of a single file size of up to 2TB file storage, therefore, the most direct way to solve this problem is to convert our u disk format from fat32 to ntfs will solve the problem.

This is a system problem, all USB drives are like this. If you store more than 4GB of individual files, please change the default format.
