About saving Camtasia recordings (.cmrec)
Camtasia recording files (.cmrec) contain the action recorded on the screen, as well as any audio and camera video recorded by Camtasia.

When you save a project, Camtasia saves a copy of the recording file with the project.
To share projects across computers, select the Save as a Standalone project file when saving the Camtasia project (.cmproj) to include all media in the project file.
