How to remove space character (whitespace) from end of filenames and foldernames?

Problem with mac is that it allows space character at end of file or folder. If this file or folder with space character in end is beeing copied to FTP using Filezilla or Dropbox then mac makes folders with "Foldername_WhiteSpaceConflict" To get rid of this problem all files and folders with space character needs to be renamed without space character. What solution could be the best using terminal or some program?
