A G2M file is a temporary recording created by GoToMeeting, a professional video conferencing application. It contains a recording of a video session. G2M files must be converted to a .MP4 (Windows and Mac versions), .WMV (Windows version only) or .MOV (Mac version only) file in order to be viewed.

After you end a GoToMeeting session, the program's "Recording Manager" automatically opens, which allows you to convert your G2M file to the MP4, WMV, and MOV formats. If it does not open automatically in the Windows version, right-click the daisy icon in the system tray and select Convert Recordings. If it does not open in the Mac version, select GoToMeeting → Preferences → Recordings in the Finder menu. The G2M file is not playable until it is converted.
