Ultralite PDM enables CAD collaboration and a lightweight product data management workflow on Google Drive™ by automating the generation of FreeFileSync configuration files.
The standard Google Drive™ sync app is not designed for collaborative CAD work. Virtual drives can impact performance, background syncing creates unpredictable conflicts, and inconsistent file structures can break assembly references. Traditional enterprise PDM systems solve these issues, but they are often expensive and overly complex for small teams.
Ultralite PDM provides a practical alternative designed for small, fast-moving engineering teams. It uses Google Drive™ as a secure central project repository and FreeFileSync for deliberate, user-controlled synchronization between workstations.
The Workspace add-on does not perform synchronization itself. Instead, it automatically generates ready-to-use FreeFileSync configuration files tied to the user’s Google account, selected project folder, and local workspace location. These configuration files ensure every team member uses the same folder structure and sync rules.
On first synchronization, FreeFileSync creates the correct local project directory automatically, enabling rapid onboarding and consistent collaboration across the team. Every sync is explicit and intentional, giving users full control over conflicts and preventing accidental data loss.
Key benefits:
 • Automated FreeFileSync configuration
 • Assembly-safe CAD workflows
 • Consistent folder structure across users
 • Explicit, conflict-controlled synchronization
 • Works with any CAD software
 • Lightweight alternative to traditional PDM
 • Secure Google Drive™ storage
Ultralite PDM is ideal for startups, hardware teams, and independent engineers who need predictable collaboration without heavyweight infrastructure.
