Can’t copy my large file to a FAT32 SD card

Hello, guys! My computer is running with Windows OS. Now, I’m trying to transfer a 5.02GB file to a 32GB FAT32 formatted SD card. But it says that the file is too large for the destination file system and offers two options: Skip or Cancel.

File Too Large

What does file too large for destination file system means? There is still 20 GB free space on the SD card. How can I resolve this issue and move the file to SD card?

Solutions for file too large for destination file system error

The error appears because of file size limit of FAT32 file system. When a drive is formatted with FAT32, it won’t allow you to put an individual file over 4GB on it. To fix the error and transfer files in a success, it’s advised to change the file system of your SD card, USB flash drive or external hard drive from FAT32 to NTFS or to exFAT.

Both of NTFS and exFAT breaks the 4GB file size limit of FAT32. NTFS performs better in data security, read & write speed than exFAT. In compatibility, NTFS is fully supported by Windows XP and its later versions, and Microsoft Xbox One; exFAT has better compatibility, which can be used on almost all version of Windows, Mac OS X, Xbox One and PlayStation 4. If you want your drive has higher read & write speed, convert to NTFS; otherwise, change to exFAT.
