Can I convert external hard drive to NTFS without formatting?

“I get an error saying that the file is too large for the destination file system when I try to copy 5.02GB file to my external hard drive. After researching on internet, I know that I can change the file system of my external hard drive from FAT32 to NTFS as FAT32 formatted drive doesn’t support to store file beyond 2GB. I can format the external drive to NTFS within Disk Management. But there are some files on it and I don’t want to lose them. Is there a way to convert it to NTFS without formatting?”
