OSS: OneDrive Explorer

In enterprise cloud storage environments, especially for large datasets stored on OneDrive, management and analysis through standard interfaces were not sufficiently detailed. There was a need for deeper analysis of file structures, metadata, and content relationships.

To address this need, OneDrive Explorer was developed as a tool that makes OneDrive data more transparent, analyzable, and auditable.

Technically, the project:

  • Is developed using Python
  • Accesses OneDrive data via the Microsoft Graph API
  • Processes data and generates outputs in JSON format
  • Is optimized to handle large-scale datasets

The tool provides the following capabilities:

  • Detailed extraction of OneDrive file and folder structures
  • Metadata analysis (file size, creation date, ownership, etc.)
  • Exporting and reporting of data structures

Key problems solved by this project:

  • Provides visibility into data that is not accessible through standard UI
  • Enables data extraction for digital forensics and audit processes
  • Significantly reduces analysis time for large-scale OneDrive structures

Additionally, the project:

  • Can be integrated into various analysis pipelines thanks to its script-based nature
  • Allows easy extension for new analysis scenarios due to its modular structure
