#2 Why do I get the "file too large to fit on volume" error?

The reason for the "Cannot copy because the file or folder is larger than the disk format allows" error is that you are trying to transfer the file to a USB or hard drive formatted with the FAT32 file system, which only supports partitions up to 32 GB in size and individual files up to 4 GB.

This happens when you try to copy a file larger than 4 GB from your computer or Mac to a USB drive, SD card, or other memory card formatted with FAT32. This is due to a limitation of the FAT32 format.

In this case, you need to format the device to exFAT (eXtended File Allocation Table) or NTFS (New Technology File System). Learn about the differences between FAT32, NTFS, and exFAT.

Fixing "File Too Large for Volume's Format" on Mac

If you encounter volume format issues when copying files between your Mac and a USB drive, you can reformat the drive to exFAT.

exFAT is a file system introduced by Microsoft for use in USB flash drives and is compatible with macOS. It addresses the issue of files larger than 4GB that are not supported by FAT32 and other formats. For flash drives, exFAT is more suitable than the NTFS file system.

This guide is about formatting a USB flash drive to exFAT on a Mac; if this section resolved your issue, read on, and don't hesitate to share this article to help more users.

Compared to the FAT file system, the theoretical maximum volume size for exFAT is 64 EB, with the currently supported maximum volume size being 128 PB. The maximum size for a single file is 16 EB, and the maximum number of files in the same directory is 2,796,202.

2. How do I change the volume format of a USB? To modify the volume format of a USB device, you typically need to make adjustments on your computer. Here are the general steps: 1. **Connect the USB Device**: Insert the USB drive into a USB port on your computer. 2. **Open File Explorer**: On Windows, click the folder icon on the taskbar; on a Mac, open Finder. 3. **Locate the USB Device**: In File Explorer or Finder, find and double-click your USB device to open it. 4. **Check the File System**: Ensure that the file system of the USB is FAT32, NTFS, or exFAT, as these formats support audio files. If it's not one of these, you might need to reformat the USB (which will erase all data, so back up important files first). 5. **Change Volume Format**: By "volume format," it's often referred to as the audio file's encoding format, like MP3, WAV, AAC, etc. You'll need an audio conversion software (like Audacity or Format Factory) to convert your audio files to the desired format. 6. **Convert Audio Files**: Open the conversion software, select the audio files to convert, choose the target format, and initiate the conversion. 7. **Save to USB**: After conversion, copy the newly formatted audio files onto your USB device. Note that "volume format" could also refer to volume levels or gain settings in some contexts. If that's the case, you might adjust the USB device's volume through an audio player or your operating system's settings.

Plug the USB into a Windows computer. In File Explorer, open the USB and back up any important files elsewhere. Right-click the USB and select "Format." Set a new file system format for the USB, then click "OK."

What can I do if the file is too large to copy?

1. First, change the file system of the target device to NTFS or exFAT. 2. Use a file transfer software like Todo PCTrans to move all files in one go. 3. Compress oversized files beforehand, if necessary.
