Detailed Description

Version 1 container header placed at offset 0 for legacy / initial format.

Field summary:

identifier: magic signature (AARU_MAGIC) identifying the container.
application: UTF‑16LE creator application name (fixed 64 bytes, zero padded).
imageMajorVersion / imageMinorVersion: container format version of the file itself (not the app).
applicationMajorVersion / applicationMinorVersion: version of the creating application.
mediaType: media type enumeration (MediaType).
indexOffset: byte offset to the first index block (must be > 0).
creationTime / lastWrittenTime: 64-bit Windows FILETIME timestamps (100 ns intervals since 1601-01-01 UTC).

Definition at line 76 of file header.h.
