STG_S_CONVERTED

Successful conversion with a changed representation

STG_S_CONVERTED is a success HRESULT, but it carries more information than S_OK. It can result from STGM_CONVERT when an existing file, stream, or storage element is converted into COM structured storage. For IStorage::CreateStorage, an existing stream can become a storage that contains a stream named CONTENTS.

The caller must continue using the returned IStorage object and must not assume the underlying object retained its former flat representation.

What to verify

Test HRESULTs with SUCCEEDED/FAILED; comparison only with S_OK incorrectly rejects this result.
Record whether STGM_CONVERT, direct mode, or transacted mode was used.
Reopen the converted object through structured-storage APIs instead of parsing it as the original flat file.
Understand when conversion becomes durable: transaction and commit rules still apply to the returned storage.
