Relax directory entry modification time validation #346
Conversation
- Problem Many legitimate Office files (created by Google Docs, Wine-based applications) fail to open due to strict ModifiedTime validation for streams. - Solution Move ModifiedTime validation under `#if STRICT` directive, consistent with existing CreationTime validation approach.

@SteAmeR Are you able to provide steps to create the sample file? I'd like to include a sample for the unit tests if/when strict validation gets implemented, but I'd rather include one that I created myself so I can label the client origin etc. if that's OK? |

Just to clarify, under issue #312 I explained the reason why I requested this PR — it is mainly to avoid unnecessary exceptions when reading real-world legacy files that don’t strictly follow the MS-CFB spec but are still accepted by Word/LibreOffice. If possible, I’d kindly ask you to consider merging this PR, as it would help make OpenMCDF more tolerant in read/view scenarios while keeping strict validation available for file creation. Thanks again for your efforts on maintaining this project. |
