A backup in the same Folder as the original is not very sound.
If something happens to the original, you loose every thing including your backup.
I can't for the life of me figure out why you would have a backup in the first place? After all, this is a program. As long as you have the install program, no backup is needed.
The ini file is different, it's like data created by a progam and is something that can change and if changed incorrectly, can effect the operation of the program itself.
By the way, Weatherbug can contain Adware,Spyware so be careful.
