And a very good thought too. Although it only partially gets me forward. I deleted all the files from the backup folder and then I made a SEQ file save. The save was successful in that no errors were generated. I looked in the backup folder and the backup was now present and the new SEQ file was also was also available.

I now go and save the SEQ file again, RB goes through the process of saving and then, at the end of the progress bar, the error message regarding TMP and SEQ was generated. I looked in the backup folder and only the previous backup file was present - which is what you suspected.

So I delete the backup file from the folder and then save the SEQ again. This time the save is error free and the backup file is now in its folder and the new SEQ file is also present.

I now go back to RB and disable the SEQ backup feature. Now I can save SEQs until the cows come home with no errors. I'm quite happy with this as long as I remember that backups are not being made.

So I'm not sure why this might be the case, I certainly can't find any settings that would help.

Thanks for the steer in that direction though.
