The operating environment of this tutorial: Windows 7 system, Dell G3 computer.

U disk, as a portable mobile storage tool, has played an important role in our lives, but we often encounter that when copying some files to the U disk, the U disk space is obviously missing. There is also a large file, but it prompts that the file is too large and cannot be copied. What's happening here? How to deal with it? Let me introduce it to you below.

First of all, popularize some knowledge. U disks generally have file systems, mainly in three forms: NTFS, FAT16, and FAT32. The three forms correspond to different sizes of single files, as follows:

  • NTFS: Maximum file 2TB

  • FAT16: Maximum file 2GB

  • ##FAT32: Maximum file 4GB

Generally, the default U disk is FAT32. FAT32 is a type of hard disk partition format for Windows systems (common ones include FAT16, NTFS, exFAT, etc.). It uses a 32-bit file allocation table. Although Based on FAT416, its disk management capabilities are greatly enhanced, but it has a feature that the maximum single file size supported is 4GB.

So when we copy a single file that exceeds 4G, the system will prompt that the file is too large and cannot be executed. It does not mean that the capacity of your USB flash drive is not enough.

Solution:.

Here you can see that the drive letter of the U disk inserted by the author is G. drive, right-click the G drive and select Properties.
