What is an OSS file?

OSS files mostly belong to Microsoft Outlook. Your OSS file can be one of two specialized data files.:

Outlook Item Storage File: This file uses a Microsoft Compound format to store email items, calendar entries, and contacts. It is managed by Microsoft Outlook and serves as a local backup of your messaging data.

Optical Surface Scan File: This file holds scan data from optical surface measurements. It is used in specialized projects and is associated with OpenSees. For more details, visit OpenSees.

FilExt.com note: The same OSS extension is used for both uses. Open these files with the appropriate software to view and manage their contents.
