Notes about the FCX 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 FCX file type is primarily associated with 'Vax VMS'. An FCX file is an archive file with versions of the FCX.exe program on mainframes and PC's. It was used to compress files and folders for transmission between mainframes and PC's. If you specifically need to access .FCX archives on a PC under Windows there is a commercial product that claims to do that: Thoro'Pac.
