Key Points

To examine how OneDrive's Files On-Demand and Known Folder Move mechanisms disrupt traditional file access assumptions in business desktop software, and to outline technical mitigations.
Analyzed failure modes, such as 'file not found' errors during data import, caused by unhydrated placeholder files.
Evaluated filesystem attribute checks and programmatic methods to identify offline placeholders versus fully downloaded local files.
Reviewed remediation approaches achievable at both the application codebase level and enterprise IT administrative policy level.
Identified that legacy business applications often fail when attempting direct file handles on un-downloaded cloud placeholders.
Determined that applications can prevent crashes by querying file system attributes to detect placeholder status before initiating read operations.
Outlined administrative and configuration controls that IT departments can apply to enforce hydration policies for critical business directories.
