Edit: I have mistaken dropbox for gedit's default backup feature, see below.
As the title says when I create a file in any dropbox synchronized folder it creates an unhidden (no . prefix) duplicate backup file with a ~ after the original name.
For example, if I create a file file1, dropbox creates a backup file1~.
This drives me crazy in editors with tree navigation menus and litters the folders in general. I would be very thankful if someone could suggest a possible solution to this (either how to hide the backup files or get rid of them altogether).
