When using the file-based approach in the SAP S/4HANA Migration Cockpit, there are two distinct file size limitations for data uploads. The compressed ZIP archive containing the data files must not exceed 160 MB. Additionally, each individual XML file contained within that ZIP archive has its own separate size limit of 100 MB. Both constraints must be met for a successful upload. This ensures that both the overall package and its individual components are within the system's processing limits.

B. 160 MB per file: This is incorrect. The 160 MB limit applies to the entire compressed ZIP archive, not to the individual uncompressed files within it.

C. 100 MB per ZIP file: This is incorrect. The 100 MB limit applies to individual XML files inside the archive, while the limit for the ZIP file itself is 160 MB.
