The website shows that it is supported, but I can't find it in the File Opts. I'm trying to understand how to add a custom file type, but I'm having a hard time and not sure if it is necessary.
Not sure if it makes a difference, but I have the exact filename and location where it used to be (folder was deleted too with it though). And it was deleted a bit less than 24 hours ago.
I so hope it can be done otherwise I lose months of work

Thank you so much in advance!
