Problem solved - my own mistake - I was calling the file delete (f_unlink) function from a background task, not main line code.

The function will return if I give it the wrong / non-existing filename.

However, if I give it the filename of an existing file, it doesn't return. I have a watchdog implemented which isn't kicking in - so I need to investigate more.

Maybe try (assuming file exists):

fresult = f_unlink("FILE1.TXT");

f_result = f_unlink(fno.fname);
