Notes about the AF3 file extension:
Incorrect file associations could be the result of underlying issues within your PC system. As such it is highly recommended to scan your PC for invalid registry entries
, unused processes and other unfavourable system settings to identify slowdown issues.
The AF3 file type is primarily associated with 'FlowCharter' by iGrafx LLC. Was Micrografx FlowCharter and ABC FlowCharter before that. The newest version has read/write support for the .AF3 filetype.
