libolecf is a library designed to access and parse OLE 2 Compound File (OLECF) format files. The library enables reading of various file types that use the OLECF format, including certain versions of Microsoft Office documents, thumbs.db files, and other applications that utilize this compound document format. The library provides programmatic access to the internal structure of OLECF files, allowing developers and forensic analysts to extract and examine the contents of these compound documents. It supports parsing the directory structure, streams, and metadata contained within OLECF files. Currently in alpha development status, the library is released under the LGPLv3+ license. Future development plans include implementing multi-threading support to improve performance when processing large files or multiple documents simultaneously. The library serves as a foundation for digital forensics tools and applications that need to analyze Microsoft Office documents and other files using the OLE 2 Compound File format for evidence collection and examination purposes.
