Perhaps the codec for Fujifilm .RAF (X-S10) was not updated. Try this:
https://fujifilm-x.com/global/support/download/software/raw-file-converter-ex-powered-by-silkypix/
Install this one from Fujifilm, it should have all of the up to date codecs.It is free, plus, you get a decent raw converter program.
I should have explained. If I remember correctly, you enter the new file name you want (I found this fiddly) at the select folder stage. It isn't created till you take the next photo, which will store in it. After that you can select either folder.
