Really sorry for the lack of detail, I wasn’t thinking ..
ok main pc is win 10... select files from drive on my pc, drop relevant “type” of file into correct folder on unraid via lan...
I think I may have change the most free option to see if it changed how it distributed the files.
any files that I put on the system continue to stay on the same disk, I’m thinking I have to “physically” put the folder on the other drive to move it ?
whilst I have no issue in building things pc related hardware wise, sometimes the software manages to screw my head up ... once again sorry for not enough detail in the 1st reply, lack of thought on my part totally .. thanks for helping it is very much appreciated...
