IMAPI_E_DATA_TOO_BIG

IMAPI_E_DATA_TOO_BIG is a per-file representation limit, not a total-disc-capacity error. IMAPI2FS can generate ISO 9660, Joliet, and UDF images, and a source file that fits the media may still exceed the maximum size representable by a selected file-system revision or format. The built-in message names the limiting file system.

Compare the single file size with the active output formats

  • Record the affected file path and exact stream size.
  • Record FileSystemsToCreate, the UDF revision, and ISO 9660 settings used for the result image.
  • Distinguish this error from IMAPI_E_IMAGE_SIZE_LIMIT, which concerns the total configured image block budget.

Splitting the file, selecting a more capable output file system, or changing the application package layout can be valid fixes. Increasing FreeMediaBlocks alone cannot make a file representable in a format whose per-file limit has been exceeded. When emitting multiple file systems on one disc, validate large files against every selected representation before adding the complete tree.
