I have a slide show on a CD but I can't open it on my iMac. This message pops up when I double click the file: "The document “.................fms” could not be opened."
What program(s) might open it? Have searched but all the solutions that appear are for "Windows" files.
You might like to try Handbrake, an open source video transcoder. It can transcode many old video formats.
Amendment:
I had assumed from Tony's comment that this was a video format but some research on the internet reveals it to be a spreadsheet programme, late of Lotus 1-2-3 origin bought out by IBM. This link may help:FMS Formats
Thanks Rick. I have tried 'Handbrake' but get: "No Valid Source Found”. My file is not a spreadsheet. It contains 23 of my images, as shown by "Quick Look".
