Practical Examples and Case Studies
Consider the case of a user attempting to transfer a large video file from their Mac to a FAT32-formatted USB drive. They encounter error code 36 due to the file being larger than 4GB, which exceeds FAT32’s file size limit. Switching to a drive formatted with exFAT or NTFS resolves the issue, allowing for the successful transfer of large files.
