I have just seen the long list of Dropbox file and folder recommendations, which is basically a do-not-use list of four main headings which include 20+ forbidden file and folder names. I had just signed up for a 2TB account, which I will not renew if this does not get fixed. I use other cloud backups and none has this problem. I wouldn't have the time to go back and rename all my files that may use a dash (-), asterisk or other symbols. Sometimes the folder itself will be rejected, but if you select the files in inside the folder and drag THEM into dropbox into an identically named folder, they'll go in no problem. This must be fixed. Who has time to make all these corrections?
