I agree that it is annoying to occasionally have to remove special characters from file names. BTW, I also back up locally so a OneDrive error would be a real nuisance, but no real damage. I mainly like cloud storage for devices with small SSD drives, like my old MacBook Air.

I used to be a very happy Dropbox paying customer but I did not like their hiring of C. Rice to their board of directors.

edit: thanks for the good reply to my comment.
