├ wallpaper
│ └ <width>x<height>.bmp
├ logon
│ └ background<width>x<height>.jpg
├ setup.ins ← Made by bbz_edv
├ getmaxresolution.exe ← Made by bbz_edv (Written in C++)
└ ResSwitch.exe ← Made by Naughter Software [[http://www.naughter.com/]]

1. The backgroundfiles are stored in folder “wallpaper” and they have to be a .bmp-file, otherwise it will cause problems with Windows XP.
2. Windows XP: Logonscreen- and desktopbackground are the same and stored in folder “wallpaper”
3. Windows7: Logonscreenbackgroundfile is stored in folder “logon” and has the following restrictions:
   1. backgroundDefault.jpg ← would be used by Windows in case no other backgroundfile is available.
   2. background1024x768.jpg
4. Windows 7: desktopbackgroundfiles are stored (like in Windows XP) in folder “wallpaper” and have to be a “.bmp”-file, too.

1. Die Hintergrunddateien müssen im Ordner “wallpaper” abgelegt werden und müssen eine .bmp - Datei sein, weil es sonst Probleme mit Windows XP gibt
2. Windows XP: Anmelde und Desktophintergrund-Dateien sind ein und dieselben und liegen im Ordner “wallpaper”
3. Windows 7: Anmeldehintergrund-Dateien liegen im Ordner “logon” und unterliegen folgender Namenskonvention.
   1. backgroundDefault.jpg ← Wird von Windows nur genommen falls keine passende Dateie vorhanden ist
   2. background1024x768.jpg
4. Windows 7: Desktophintergrund-Dateien liegen wie bei Windows XP im Ordner “wallpaper” und müssen ebenfalls eine .bmp - Datei sein
