Things I hate in relation to software:
Application Data
This is a folder that is commonly mis-used, It should store data related to the application (For example: user preferences) and is not a location where you can save files from the application.
My Documents
This is a default location where user files should be stored. Not Application data, program files ect.
Creating Folder in My Documents
There is no need to create folders that may never be used, wait till the folder is actual
