Final answer:
The question pertains to file formats and their support for file sizes, with an emphasis on the fact that most file format size limitations are related to file systems or applications, not the formats themselves.
Step-by-step explanation:
The question seems to be asking about which file format can support a certain file size. However, the question is slightly unclear as most file formats do not have a size limit inherent to the format itself; rather, file size limits are often imposed by the operating system, file systems, or specific applications. For example, the FAT32 file system can only support files up to 4 GB in size, whereas NTFS, used in more modern Windows operating systems, can support files much larger. In terms of document files, older formats like .doc had size limits, whereas newer formats like .docx can support larger files.
