File type: Various data file
An oc5 file contains event data for openCanvas, a digital painting application suitable for beginners to advanced users.
It stores data associated with the drawing process rather than serving as a standard image file.

The oc5 file extension is used by openCanvas, a painting application for Apple macOS and Mac OS X, for event data created with version 5 of the software.
Event data records actions from a drawing session and can be used by openCanvas to reproduce the work.
Open an oc5 file with openCanvas on Apple macOS or Mac OS X.
Because this is an openCanvas-specific event file, general image viewers and editors may not be able to open it correctly.
An oc5 file is not normally converted directly because it stores openCanvas event data rather than a standard image. Open it in openCanvas and export or save the resulting artwork in an image format supported by that application.
Exporting the artwork preserves the finished image, but not necessarily the recorded event history.
