How to fix 'File Too Large' error when copying files on Windows

Copying files in Windows usually works fine for small files. However, when trying to copy a file larger than 4GB, you may get the "File Too Large" error. The most common cause is that the destination drive is formatted as FAT32, which only supports files up to 4GB.

Instructions for "File Too Large" error when copying files on Windows

Step 1: The first step to convert FAT32 format to NTFS to fix errors when copying files on Windows is to right-click on the connected hard drive or USB, then select Format to reset the format.

Step 2: In the Format window, find the File System section, change from FAT32 to NTFS, then click Start to begin the USB reformatting process.

Step 3: The system will display a warning that the formatting process will erase all data on the USB. If there is important data on the USB, back it up before continuing.

Step 4: After the formatting process is complete, your USB or hard drive has been converted to NTFS format.

Step 5: Now you just need to select a file larger than 5GB and try copying it to the USB or hard drive that has just been converted to NTFS.

With just a few simple steps, you have successfully fixed the "File Too Large" error when copying files on Windows, making it easy to move files larger than 4GB to USB or other storage devices.
